In light of the depletion of fossil fuels, it is necessary to implement energy efficiency techniques and policies that support sustainable development. Globally, researchers show more interest in discovering fossil fuel alternatives, as a result of fuel crisis. This research elaborates on the production and experimental investigation of briquettes made from ideal municipal solid waste (MSW), such as food waste and garden waste, as a feasible choice for alternate fossil fuels. From Municipal, agricultural, and food waste, we can get biomass waste. Municipal solid and agricultural waste is extensively dispersed, but their potential for converting biomass into energy generation still needs to be explored. This study was carried out based on the information gathered from various studies published in the scientific literature. It also details the methodology of valorizing wastes into energy by densification, such as briquetting. At different ratios, the physical and chemical characteristics of food waste/ garden waste briquettes have been examined and contrasted with commercially available ordinary coal. The results also revealed that increasing sawdust ratios would boost the briquettes compressive strength and calorific value. In addition to being a viable biomass fuel, food waste/garden waste briquettes have proven that they may be utilized to manage MSW. The carbon footprint and global environmental consequences can be reduced using waste-based briquettes. The finding of this research is considered a satisfactory alternate fuel and can be used for sustainable development.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141633","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}

Because of its characteristics, this PHSS is exclusively adopted in numerous engineering uses such as nuclear, chemical and marine industries. Welding is one of the important methods of joining that helps to make weldments with better performance characteristics. Corrosion behaviour is one of the important characteristics that contribute hugely to marine and other corrosion-related environments and also this is the most common problem for most of the manufacturing industries. The goal of this study was to analyze the PHSS weldments’ corrosive behavior and compare it with that of the two commonly used welding processes, namely MIG and TIG. The corrosive properties of the weldments were evaluated using various mediums, such as nitric acid, ferric chloride, and Oxalic acid. The weight loss procedure was utilized to calculate the PHSS weldments’ corrosion rate. The results of the study revealed that the corrosion rate has increased with time. Temperature variations were identified as the primary cause of this phenomenon.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135142178","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}

For the car to operate at peak performance, a well-designed radiator-sidepod system is essential such that it can dissipate heat generated by the engine faster, for the car to run in optimal performance. Testing the car physically for various radiator-sidepod design iterations is a very difficult task, also considering the costs to manufacture the radiator-sidepod setup. The objective of this study is to develop a comprehensive methodology for analysing heat transfer through radiator setup using Computational Fluid Dynamics and to validate it through experimental investigations, to enhance performance and efficiency of the radiator setup. It further explains how to find out its heat transfer efficiency, and to choose the right radiator-sidepod setup, giving optimal performance. The flow of coolant inside the radiator, as well as external air flow through sidepod, is considered for realistic results in numerical analysis. Various radiator dimensions and sidepod designs are considered in the scope of this paper. The heat transfer simulation is performed in ANSYS Fluent, and their results compared. The final radiator-sidepod setup concluded as optimal setup in this study provided an average temperature drop of 2.9 °C through experiment and 2.72 °C through numerical analysis, providing uniform airflow through the radiator face with less dirty air.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":"22 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135091410","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 main advantages of using e-mobility are operational flexibility, lower carbon emission and regenerative energy. Thermal management in an e-vehicle plays a vital role for the reliability of the system and any thermal failure can cost a significant amount of money to a company per vehicle. Inverter assembly is widely used to convert Direct Current (DC) to Alternating Current (AC) in the e-mobility platform to operate the motor for vehicle propulsion. It consists of various electronic transmitters, controllers, capacitors, and semi-conductors which will emit an enormous amount of heat during their operation. Since inverters are highly temperature sensitive in nature, it is necessary to improve the temperature distribution in the device. For this reason, adequate cooling system and ventilation is inevitable to keep the components operational. In this study, the thermal characteristic of the inverter was determined using transient thermal analysis considering three different fin geometry used in the heat sink. The two major heat sources are capacitors and Insulated Gate Bipolar Transistor (IGBT), and the heat transfer in the inverter assembly is due to conduction, convection, and radiation. This paper deals with the optimization of inverter fin to meet the cooling efficiency. Also, experimental validation was performed to verify the simulation results and correlation study was carried out to find the results accuracy of the numerical method. Simulation methodology was standardized for the thermal management of an inverter which can be effectively used in the electric vehicle industry.</div></div>","PeriodicalId":38377,"journal":{"name":"SAE Technical Papers","volume":" 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135141147","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}

Therefore, there is a significant need to investigate and analyse these materials to facilitate their effective application in manufacturing sectors. This study investigates the machinability of drilling AA6061 using a micro-textured tool and proposes an Adaptive Neuro Fuzzy Inference System (ANFIS) model for investigating the machinability of drilling AA6061 aluminium alloy with a micro-textured uncoated tool. The ANFIS model considers various input parameters such as spindle speed, feed rate, and Coolant type to predict the machinability performance of the drilling process. The results indicate that the ANFIS model is an effective tool for predicting the machinability performance of AA6061 during the drilling process.
