It is prescribed for any industry to manufacture an optimized design of strap joint and duly test it before making an entry to the market. There is no standard method available to be followed by the industry for strap validation at an earlier stage. Most of the strap joint designed and tested based either on MAST test (done in the later stages) or on the experience. So, to test the strap joint at an earlier stage there is a need to design a component level strap joint validation method with a goal to assess the durability of strap joint vulnerable to fatigue failures due to vibration over-amplification in a bracketed after-treatment assembly while able of detecting any design flaws and eliminating or reducing numbers of potential test induced failures. The objective of this work is to define and document a systematic approach for component level strap joint validation method used to mount after treatment system components. Due to geometrical complexity and nature of material, geometrical nonlinearity and material nonlinearity were considered in the analysis. Also, for getting the most realistic results contact nonlinearity was also considered. And finally, out of various approaches investigated, an approach which was able to replicate failures in a more exact manner comparable to assembly level test was recommended as the component level strap validation method.","PeriodicalId":356647,"journal":{"name":"Indian Journal of Production and Thermal Engineering","volume":"138 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140485000","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 experimental investigation was done after the CFD ANSYS Fluent simulation of different parameters based on the uniformity temperature and air flow distributions on the symmetry plane. The performance of the designed solar dryer was compared with that of the open sun dryer method, based on drying rate, moisture ratio, and moisture content on a wet and dry basis. From fourteen different mathematical drying thin layer kinetics models, the maximum correlation coefficient of 0.999574, the minimum root mean square of 0.0001352, and the minimum reduced chi-square of 0.007353 were obtained for the Verma et al. model for the slice banana in the designed active solar dryer. Recycling the air from the outlet of the drying chamber on the first day is not possible because the quality of the air is lower when compared with ambient air. The outlet air temperature and relative humidity of the drying chamber were 4.39℃ higher and 8.24% lower than the ambient air temperature and relative humidity respectively, so it is possible to recycle the air after the first day. The average moisture content removed from the product in the designed solar dryer and open sun dryer was 68.01% and 51.01%, respectively, in the 22 and half5 drying hour. The difference between the maximum and minimum moisture removal was 4.47%. It indicates there is a uniform drying in the designed solar dryer. The overall solar air collector efficiency was 33.80%and the maximum drying efficiency was 31.10 %.","PeriodicalId":356647,"journal":{"name":"Indian Journal of Production and Thermal Engineering","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125191802","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}

Woody biomass pellets are gaining popularity in the primary energy industry. Agricultural biomass is either burned on the farm or used as fodder for animals recently, which releases toxic chemicals in environment. Locally cultivated crop waste has potential to be more environmentally benign than imported biomass. As a result, residues of locally grown Cotton, Tur, and Soybean crops were used for pelleting in this study. The collected residues were sundried and shredded to particle sizes ranging between 2.36 mm to 4.75mm. The pellets were prepared without binder by using pelleting machine. The proximate and ultimate analysis of crop residue and pellet samples was carried out to check characteristics and applicability of pellets as bioenergy source. The thermogravimetric analysis was conducted to check thermal behaviour and SEM-EDS analysis was carried out to detect the inorganics present in ash sample. The obtained calorific values of cotton, tur, and soybean pellets are 3696.57, 3487.83, and 3281.65 Kcal/Kg respectively and moisture content is below 10% for all three types of pellets. The findings showed that crop residue pellets as an alternative to conventional fuel sources provide superior economic and environmental outcomes.","PeriodicalId":356647,"journal":{"name":"Indian Journal of Production and Thermal Engineering","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122711669","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}

Renewable energy sources will certainly become more prominent. Modern civilizations need cheap, plentiful energy to survive, therefore, it is crucial for human civilization to create a sustainable, affordable, and environmentally benign alternative sources of energy. The global energy dilemma may have an efficient solution in the form of wind power. In current state of affairs, the air could seem like insignificant to any or all. However, we tend to all grasp that, the planet has shaped up with associate uneven surface, which suggest that the sunrays could strike these surfaces with variable intensities at numerous spot on its uneven surface. This creates associated degree of unequal degree of heating of the earth surface, that which causes variation in part of atmospheric pressure thereon. Then it leads to wind. The Kinetic energy of these air molecules is nothing but wind energy. A mechanical mechanism known as a wind turbine which transforms, kinetic energy which is there in the air around it into the required form of mechanical energy. Here in this research, we focused on the repellent qualities of permanently magnetized objects with similar poles. These innate qualities of magnetic propulsion are used here as an energy sources. Due to the inclusion of this components like magnetic repulsion, our VAWT system will operate more effectively even at lower wind speeds circumstance also. This magnet will produce a repulsive force that will add various sorts of kinetic energies to the wind turbines as they convert wind energy's kinetic energy of into the necessary mechanical power when it’s employed as an extra source of energy in a VAWT.","PeriodicalId":356647,"journal":{"name":"Indian Journal of Production and Thermal Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121966280","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 outputs of PR2 in m3 /m3 and vol.% were compared with gravimetrically measured soil moisture. The R.M.S.E. measurement at Site A at the first and second replicates increased from 0.49% to 0.67%. In contrast, the r2 value of 0.99 was obtained for the two replications when comparing the soil moisture content observed from gravimetric measurement and the automated outputs from the PR2 Probe soil monitor. The R.M.S.E. values were 0.48%, and 1.32% were estimated for the first and second replications at Site B.

It is projected that 33% of the worldwide people will be highly water-stressed by the 2050s if effective strategies are not developed. The study assessed urban domestic water demand and supply in Edo North senatorial district in Edo State, Nigeria. This is with the view of exploring some critical water resource variables to determine water security, distribution, and accessibility of safe drinking water in Edo North in Edo State in Nigeria. Integrated Water Resource Management Tools (IWRT) such as Water Poverty Index (WPI) and Water Accessibility Indicator (WAI) was applied. The results show that Auchi is highly water-stressed at the Estako-west area with MPI and WAI values of 0.24 and 0.33. Conversely, Okpella and Agenebode in Eskako central have MPI and WAI values 0.34 and 0.31, and 0.31 and 0.32. Sabo Gida Ora and Isobe in Owan East and West have better safe drinking water coverage and accessibility with the indicator values of 0.54, 0.53 [WPI], and 0.61 and 0.59 [WAI]. It is generally observed that the supply of potable water in the Edo North is highly unsecured and unsustainable to meet the current and future demand. Valuable and economic time is wasted to gather water from an average closest distance of 1.3 km from home to some designated water taps. In conclusion, it is imperative to design a robust integrated water policy that should include Private-Public-Partnership (PPP) to invest in the provision of safe drinking water.","PeriodicalId":356647,"journal":{"name":"Indian Journal of Production and Thermal Engineering","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121508917","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}
