The complex nature of the fluid flow inside the impeller can give rise to cavitation which is highly undesirable. Design and operating conditions in the impeller influence the extent of cavitation. The effect of the outlet pressure, temperature and rotational speed of the impeller was studied using ANSYS CFX Computation Fluid Dynamics (CFD) software. The impeller geometry was meshed with high-quality hexahedral meshes and the y + values around the blade surface are less than 2. The k - omega turbulence model was used along with the ZGB model of cavitation. The effects of the variable parameters on the cavitation volume and the head developed were extensively studied. The numerical trends are similar to those presented in the literature. By carefully controlling the outlet pressure, the effects of increased temperature can be mitigated. Thus, it is possible to operate a centrifugal pump at higher working fluid temperatures by operating the pressure above 275 kPa.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85989701","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}

All the specifications of the vehicle were taken from Bishoftu Automotive Industry, Ethiopia. Weight reduction has been achieved by 79.48% and 66.67% for carbon/epoxy and E-glass/epoxy respectively. The modal analysis shows that the first six natural frequencies of carbon/epoxy, E-glass/epoxy and mild steel are in the ranges from 56.8Hz to 134.8Hz, 27.22Hz to 64.59Hz and 31.97Hz to 75.88Hz respectively. The first two natural frequencies for carbon/epoxy and all-natural frequencies for E-glass epoxy and mild steel are in the engine excitation range. The main disturbance is due to the road excitation which ranges from 0 to 100 Hz, which is even greater than the engine excitation. Carbon/epoxy is the best candidate that some of its natural frequencies are above the engine and road excitations as compared to steel and E-glass epoxy chassis frames.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83499747","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}

Glass and carbon fibre laminates were produced using Rotex EP-306 resin and Rotex EH-758 hardener. Adhesively bonded single lap joints were then made by using a two-part epoxy structural adhesive. Graphene was added in weight percentages of 0.1%, 0.5%, 1% and 2% into the resin and dispersed by using the method of ultrasonication. A shear test was carried to determine the bonding strength. Results indicated that joints with 0.5% wt. of graphene showed better bond strength compared to other configurations for both glass and carbon adherend. It was noted that with further increase in percentage of graphene, the shear strength decreased. Furthermore, the joints made with carbon as adherend showed better strength properties in comparison with joints made of glass adherend.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83511831","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}

Traditional machining processes are only useful for a limited number of tasks due to the detrimental effects they have on the strength and stiffness of the machined alloys. However, one of the most favoured post-processing equipment used to obtain a high-quality surface is the wire electrical discharge machining (WEDM) technology. The most crucial aspects of WEDM are the rates of the electrical current and voltage, in addition to the pulse-on and pulse-off durations. As a form of wire, WEDM makes use of brass wire that has been zinc-coated. The WEDM method is utilised in the machining of titanium alloy of grade 7 for this project. The surface of titanium grade 7 that had been processed using WEDM was analysed with a scanning electron microscope. The pictures revealed that the material exhibits homogenous solidification and a columnar grain structure along the build direction. As the pulse-on time gets longer, the Material Removal Rate (MRR) also gets higher. When the pulse-on time is set to 60 µs, the greatest MRR that can be achieved is 7.357 mm3/min. As the pulse-off duration gets longer, the MRR is getting lower. At a pulse-off time of 20 µs, the minimal MRR is reached, and it is equivalent to 5.935 mm3/min. At a peak current 6A, the highest MRR is measured is equivalent to 7.795 mm3/min.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"82 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86835944","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}

Biodiesel is a renewable energy source that can be used to reduce greenhouse gas emissions. It has emerged as a promising alternative to petroleum-based fuels due to its lower carbon footprint. However, it is important to note that the economic and energy output of vegetable oil plants that are involved in the production of this fuel is not known. Current research trends on biodiesel fuels have been investigated on non-edible oils, which present better performance when blended with diesel. This work studies the performance of karanja-based biodiesel on VCR engines with different Diesel Blending Ratio (DBR) of 0%, 10%, 20%, 30%. Engine performance and exhaust gas analysis tests are carried out on a VCR-diesel engine at various loads to examine specific characteristics of karanja biodiesel as a fuel. As per observations, DBR 10%, 20% of biodiesel exhibited better performance than the other blended fuels. To enhance the performance of DBR 10% and 20% biodiesel were graded up with the addition of 5% Methanol. The overall performance of all blended fuels is compared in all aspects.","PeriodicalId":14391,"journal":{"name":"International Journal of Vehicle Structures and Systems","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91384930","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}

The results show that the energy consumption under the condition of the transmission speed ratio optimized by the GA is 1.972 kWh, which is better than the energy consumption optimized by the weighted method and the energy consumption before optimization.
