To reduce GHGs, biomass-based biofuels containing oxygenated compounds represent a promising alternative of energy source. To convert biomass into energy, a variety of conversion processes performed at high pressure and high temperature conditions are required, and the design of such processes need as support, thermophysical property data, particularly thermal conductivity . The conventional methods to measure thermal conductivity are often time consuming and/or requires important quantities of products. Microfluidics has been proven as an appropriate support to overcome these issues thanks to its low reagent consumption, fast screening, low operating time, improvement of heat and mass transfers etc. It allows the automated manipulation, performing high throughput experimentation. In addition, over the last 10 years, a new field of investigation called \"high pressure and high temperature (HP-HT) microfluidics\" [1] has gained increasing interest, in particular for the determination of the thermo-physical properties of fluids systems[2] [3]. Currently, available methods for measuring thermal conductivity in microfluidics are not adapted to HP-HT conditions . Also, thermal conductivity data of oxygenated compounds are scarce in literature or not available in extreme conditions. Therefore, the use of alternative methods such as models, combined with microfluidics, are essential to complement experimental data.

The corresponding mixtures were proportioned, analyzed, and optimized by adopting the Taguchi approach. The binder content, CWP replacement rate by slag, alkali-activator solution-to-binder (AAS/B) ratio, sodium silicate-to-sodium hydroxide (SS/SH) ratio, and sodium hydroxide solution molarity were assigned as factors in the design phase. Each factor was characterized by four different levels, resulting in the establishment of an L 16 orthogonal array. The target design property was the 28-day cylinder compressive strength. The analysis of variance showed that AAS/B ratio, CWP replacement rate by slag, and SS/SH ratio were key factors affecting the strength in geopolymer concrete, while SH molarity and binder content showed the least contributions. The blended geopolymer made with 40% CWP and 60% slag yielded the optimal compressive strength response with a binder content, AAS/B ratio, SS/SH ratio, and SH solution molarity of 450 kg/m 3 , 0.5, 1.5, and 10 M, respectively.","PeriodicalId":385356,"journal":{"name":"Proceedings of the 8th World Congress on Mechanical, Chemical, and Material Engineering","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114358515","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}

This study was conducted during the period April - June 2019. The selection of sampling stations was done in order to the results of the study provide, a complete information on the level of pollution of these waters and the main causes of this pollution. Water samples were analyzed for temperature, pH, conductivity, total suspended solids (TSS), total alkalinity, total hardness, dissolved oxygen (DO), chemical oxygen demand (COD). All analyzes were performed using standard analytical methods (APHA, DIN, ISO). The results were processed using descriptive statistics method and compared with international water quality standards. The results obtained showed that the values of some parameters were above the allowed or recommended norms. Since the main causes of pollution of these waters are discharges of untreated urban water and those from various economic activities, or discharges of wastewaters, it is recommended: Taking measures to minimize the causes of pollution, such as improving the sewerage network of the area, the provision of a completely special system, serious investments in the treatment of untreated urban waters and those from various economic activities as well as the information of the population on the importance of protecting these waters from pollution and the consequences of these pollutions.","PeriodicalId":385356,"journal":{"name":"Proceedings of the 8th World Congress on Mechanical, Chemical, and Material Engineering","volume":"79 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130573977","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}

Among these, the most interesting from the geotechnical point of view are the study of soil compressibility [1] and the ground shear strength [2]. For this reason, in the Geotechnics Laboratory of the Universidad Politécnica de Cartagena (UPCT) an investigation that aims to delve into this discipline has been started, in order to find trends or correlations between the compressibility and shear parameters of the soil and the characteristics of the acoustic emissions generated by the relative movement of grains. The research is in its initial phase, although all the necessary equipment to carry it out is already available: in addition to the classic laboratory equipment (oedometric bench; uniaxial loading cell for simple compression; direct shear equipment), there is a multi-channel acoustic emission capture equipment (Vallen AMSY-6), to which a pair of low-frequency sensors (with sensitivity between 10-100 kHz) and another pair of medium-high-frequency (with sensitivity < 900 kHz) are connected.","PeriodicalId":385356,"journal":{"name":"Proceedings of the 8th World Congress on Mechanical, Chemical, and Material Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131280958","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 test section was a square duct with an inner cross-sectional area of 60 mm2 and a length of 1500 mm. The Reynolds number ranged between 400 and 1,600. A heater with a power of 400 W was installed at the bottom wall to heat the water at 23 °C. Thermocouples were used to measure the wall temperature at a distance of 0.16-0.58 m with an interval of 0.07 m. The ultrasonic transducer with a frequency of 28-80 kHz was set at the entrance to release the waves in a streamwise direction. In addition, the flow behaviour of the water flow induced by ultrasound was illustrated by Particle Image Velocimetry (PIV). The results showed that the heat transfer enhancement factor (HTEF) was increased when the heating wall was close to the ultrasonic transducer position. In particular, acoustic streaming was found to convect the heat transfer by swerving from the entrance to the heating wall. The maximum HTEF of 163.04% was achieved using 28 kHz ultrasonic waves at Reynold number of 400. These results would clearly demonstrate the potential of ultrasonic waves to improve heat transfer in a thermal system in the future.","PeriodicalId":385356,"journal":{"name":"Proceedings of the 8th World Congress on Mechanical, Chemical, and Material Engineering","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120957334","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}

This fluid-structure interaction problem is important in ocean engineering, civil engineering and so on. For instance, a riser in ocean has to interact with the current. Another example is a cable of a bridge, which vibrates due to coming wind. An in-house numerical model was developed using pseudopsectral methods [1] coupled with the direct-forcing immersed boundary (DFIB) method [2] to investigate this phenomenon. The model was validated first by simulations of flow through a fixed cylinder in a free stream. Drag coefficients obtained by the proposed model and other publications were compared and good agreement was found. The preciseness and convergence analysis are presented in the validation section. A solid body can be identified more precisely using the adopted PSME-DFIB model. The proposed numerical model was used to simulate the flow-induced vibration of an elastically mounted rigid cylinder. The variation of vibration frequency and maximum amplitude with respect to Reynolds number and reduced velocity was investigated in the lock-in region and compared against published literature. When solids move through grids, the coordinate transformation can eliminate noise in the resultant force, as determined by the numerical integral. In addition, the in-house PSME-DFIB model was used to investigate the flow-induced vibration of an infinitely long flexible cylinder at various wavelengths, cylinder tensions at low Reynolds numbers. A short-wavelength cylinder was considered due to the feasibility of simulations. The effects of cylinder vibration on the flow patterns were also explored in detail. Given the initial displacement, the cylinder vibration was produced a stable standing wave response in the early stage, and gradually turned into","PeriodicalId":385356,"journal":{"name":"Proceedings of the 8th World Congress on Mechanical, Chemical, and Material Engineering","volume":"234 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132522956","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}
