The aim of this study is to comprehensively evaluate the effects on performance and sustainability while employing blends of palm oil biodiesel and diesel, together with the introduction of oxyhydrogen (HHO) gas, in a diesel engine. The objectives include evaluating energy, exergy and sustainability parameters in order to ascertain the effectiveness of certain fuel mixtures. The study examined five different fuel mixtures: PB0, PB10, PB20, PB10HHO and PB20HHO. The HHO gas was injected into the cylinder alongside the air at a flow rate of 0.3 LPM. The primary results indicate significant enhancements in energy and exergy efficiency when HHO gas is used in conjunction with palm oil biodiesel, resulting in gains of up to 1.52% and 1.43%, respectively, compared to using biodiesel blends alone. In addition, the introduction of HHO gas resulted in a drop of up to 4.58% in brake-specific fuel consumption (BSFC). The use of biodiesel blends in conjunction with HHO gas led to a noteworthy decrease of up to 11.4% in carbon dioxide (CO2) and 5.7% in hydrocarbon (HC) emissions. Nevertheless, there was a notable rise of up to 9.56% in nitric oxide (NO) emissions. With the HHO-supplied condition, the combination was shown to have up to a 2.05% better sustainability index. The PB10HHO and PB20HHO blends provide improved performance when compared to pure biodiesel blends and conventional diesel. This study offers a unique approach to increasing diesel engine performance through the synergistic usage of biodiesel blends and HHO gas.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":"32 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141346090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Silica is an eco-friendly material that lowers the melting temperature which in turn enhances the fluidity of alloys. Low-cost synthesis, abundant natural resources, and mass production are other merits of silicon. In this investigation, plant-based bio-silica particles were incorporated in aluminium 7075 hybrid composites. The rice husk is rich in silica, and when it is burned or processed, it turns into ash, known as rice husk ash (RHA). After purification, the silica in RHA can be extracted using alkali fusion. Stir casting processes were used to fabricate hybrid composite material. Aluminium 7075 hybrid composites reinforced with different wt.% (0, 3, 6, and 9) of bio-silica extracted from rice husk were fabricated. Mechanical properties such as tensile, hardness, and impact were evaluated. Also, corrosion resistance was studied for the fabricated composites. The samples with different proportional values such as AlB (Al7075), AlBS1 (97 wt. % Al7075 + 3 wt. % bio-silica), AlBS2 (94% Al7075 + 6 wt. % bio-silica), and AlBS3 (91 wt. % Al7075 + 9 wt. % bio-silica) were fabricated by the stir casting process. Detailed microstructure characterization has been investigated using scanning electron microscopy (SEM). AlBS3 hybrid composites demonstrate a notable enhancement of 303.66 Mpa tensile strength and we observed a remarkable 10% increase in ductility compared to other composites. It was noticed that the sample AlBS3 shows an increased hardness of 162.4 HV and an impact energy of 26.67 kJ/mm2 due to the increased number of bio-silica particles. SEM-based fractography analysis of tensile and impact test specimens revealed the presence of dimples, cleavage facets, and intergranular cracks offering valuable insights into the failure mode.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":"45 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141345703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this material is categorized as a difficult-to-machine material owing to its high specific strength, high tool wear, and low thermal properties leading to poor machinability and poor surface integrity during machining. In order to overcome the challenges that arise during the machining of these materials, the cryogenic process, which has been very popular in recent years, have come to the fore due to the wear resistance and hardness it provides for the tool. In this statistical and experimental study, Inconel 718 was milled with cryogenically uncoated end mill (UCC) and uncoated end mill (UC) at different cutting parameters. Surface roughness, abrasive wear, cutting forces, cutting tool wear, vibration values, hardness and Build up Edge (BUE) formation obtained as a result of machining experiments were investigated. It was determined that the values of all experimental results obtained with UCCs are lower than those of UCs. Also, the second order equations (by response surface methodology (RSM)) showed very promising values of R2 (above 90%) and thus reflected the appropriate relation of the independent and dependent variables; therefore, RSM approach can be successfully implemented for predicting experimental values in milling Inconel 718 with UCCs and UCs.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":"41 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141347949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, the test specimens were prepared as per ASTM D638 using Ender 3D printer with varying infill patterns. The specimens were subjected to tensile tests in a mechanical tensile testing machine. It was observed that the specimens with linear infill patterns obtained higher tensile strength than the tri-hexagonal and lightning pattern infilled specimens.

It consists of two components, namely the filter decomposition recurrence plot (RP) transformation (FDRP) and the deep inverted residual attention network (DIRAN). A pipeline named FDRP has been designed to address the issues in the processing of data and the shortcomings of RP. Firstly, the displacement signals undergo filtering to preserve essential grinding information while effectively removing noise. Secondly, long-time series signals are decomposed and augmented based on the characteristics of the machining process. Lastly, an RP transformation is applied to one-dimensional time series data, resulting in the generation of images that accurately represent the grinding process. Furthermore, this paper proposes a novel machining accuracy prediction model. The DIRAN uses a multi-layer inverse residual network structure combined with attention mechanism to extract the features of two-dimensional RP, and its performance is better than other typical prediction methods. It can be applied to predict the polar angle of the workpiece in industrial processing and reduce the defect rate.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":"25 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141356901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, mechanical joining technology clinching offers a fast and energy-efficient procedure for assembling sheet metals, being a proper alternative to established joining methods, such as spot welding. However, the design of clinch points is a challenge, which is partly supported by numerical or data-based approaches for optimal tool dimensions assuring proper joint characteristics. While this is usually done for an ideal environment, real joining processes are characterized by multiple inevitably varying parameters, e.g. of the material, which have a significant impact on the quality of clinch points. Therefore, this contribution addresses the current gap by analyzing the effect of parameter variations or uncertainties on the resulting joint characteristics and studying the impact of the nominal tool design. Thus, an efficient meta-model-based variation simulation procedure is proposed and used for analyzing the effect of different tool design configurations and variation scenarios. Based on the results, it was found that varying process parameters have a strong impact on the resulting joint characteristics, whereby the effect significantly depends on the nominal tool design. This reveals the potential for a robust tool design and implies that the nominal tool design and the tolerancing of parameters should be done simultaneously for a reliable virtual joining point design without extensive iterations and physical tests.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":"84 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the replication of ice cores from the borehole wall holds significant importance. However, current methods face limitations such as difficulties in whipstock retrieval, extended auxiliary working hours, structural complexity, and the necessity of ice core depth calibration. To address this, this study proposes a novel method for replicating ice cores from the borehole wall utilizing a thermal coring drill bit. The design and dynamic analysis of the scissor deployable mechanism employed to drive the drill bit movement were thoroughly examined through theoretical and simulation studies. The motion characteristics of the drill bit during the replication coring process and the stress–strain behavior of the scissor rods were determined and validated through drill bit movement experiments, demonstrating a maximum error of 10%. The findings reveal that the mechanism can meet the strength requirements across three operating stages: horizontal drilling, vertical coring, and ice core recovery, with maximum loads of approximately 284 N, 749 N, and 970 N, respectively. Increasing the thickness of the scissor rods and reducing their length can augment the load-bearing capacity of the structure. Additionally, the speed transmission characteristics derived from the scissor mechanism can offer theoretical support for the drill's control system.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":"13 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141356542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study investigated the impact of blending diesel fuel with bioethanol and diethyl-ether on combustion parameters and exhaust emissions in a single-cylinder DI (direct injection) diesel engine. Both numerical and experimental analyses were used to compare the in-cylinder pressure and heat release rate of various fuel blends. Fuel spray/temperature/equivalence changes in the cylinder for different crank angles were created for different fuel types. The analysis was examined various parameters such as in-cylinder pressure, temperature, heat release rate, mass fraction burned, fuel spray formations, and equivalence ratio at variable crank angles. Results showed that all blended fuels exhibited a decrease in in-cylinder maximum pressure, temperature, and heat release rates compared to 100% diesel fuel, with an increase in mass fraction burned. CO2 emissions of D90E10 (90% diesel fuel + 10% bioethanol), D80E20 (80% diesel fuel + 20% bioethanol), D80E10DEE10 (80% diesel fuel 10% bioethanol + 10% diethyl ether) and D85E10DEE5 (85% diesel fuel + 10% bioethanol + 5% diethyl ether) fuelled engine were decreased rates 2%, 2.9%, 5% and 3.8% compared to D100 (100%diesel fuel) operation, respectively. Also, the maximum pressure in the chamber was decreased rate 3% in D80E10DEE10 fuel operation, compared to diesel fuel. Based on FTIR (Fourier Transform Infra-Red) data, the lubricating oil analyses showed that there was no significant decline in oil performance after 110 h of operation with different fuel types. However, a closer examination of the AVL FIRE program data and the EDX (Energy Dispersive X-Ray) analysis of the first ring uncovered that the wear patterns observed on the ring while using D100 fuel were heavily influenced by temperature and pressure parameters. This was particularly noticeable when compared to blended fuels that included bioethanol.","PeriodicalId":506108,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part E: Journal of Process Mechanical Engineering","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141372325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
