Significant population and automobile expansion have resulted in a rapid rise in energy demand. Because of the high demand for energy and the rapid depletion of fossil fuels, experts are concentrating their efforts on developing a suitable alternative fuel for diesel. The performance and emission characteristics of biodiesel made from watermelon methyl ester were investigated using a lanthanum oxide (La2O3) nanoparticle addition. Through the transesterification meth od, biodiesel was produced from non-edible watermelon seed oil. Compared to B20, addition of 100 parts per million (ppm) of La2O3 nanoparticles to biodiesel emulsion fuel reduces CO and HC emissions by 4.75% and 6.67%, respectively. Compared to B20 at full load circumstances, the inclusion of La2O3 nanoparticles at 100 ppm enhances the brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) by 2% and 8.8%, respectively.

In this paper, we will discuss Additive Manufacturing, which is regarded as one of the most significant innovative industrial processes in the coming years, especially in the automobile industry. As of late, the utilization of added substance fabricating (AM) in the plan has gotten a ton of consideration. To print building parts utilizing total based materials, metals, or polymers, huge mechanical arm and gantry frameworks have been created. The robotization of the assembling cycle, the serious level of plan freedom, and the subsequent extension for streamlining are altogether huge benefits of AM. We discussed all of the terms that made this technology superior to conventional production and prototyping processes in this paper. In the automobile industry, additive manufacturing is a process that follows the industries to manufacture different components.3D printing otherwise called additive manufacturing has the ability to democratize mechanical part production. 3D printing machines can find their way into all aspects of the automotive industry in the future.

In this research aimed to estimate the Overall heat transfer coefficient of counter flow Shell and Tube heat exchanger. Heat transfer is the phenomenon to analysis of heat transfer from one medium of fluid to another medium of fluid, it is considered as a major role in industrial applications. Numerous heat exchangers are available, in this research considered as shell and tube heat exchanger. Overall Heat Transfer Coefficient (OHTC) informed that three major factors are influenced as passing of fluid (film) media coefficient inside the tubes, circulating of fluid (film) media coefficient over in the shell and the resistance of wall made on metal. In this study Taguchi L9 Orthogonal array is executed to found the overall heat transfer coefficient with effective process parameters. Three major parameters are considered for this work are coil diameter (25 mm, 30 mm and 35 mm), Baffle thickness (15 mm, 20 mm and 25 mm) and Baffle gap (200 mm, 300 mm and 400 mm. Baffle plate thickness is highly significant factor for this experiment.

Nowadays ensure the performance of heat exchanger is one of the toughest roles in industries. In this work focused on improve the performance of shell and tube heat exchangers by reducing the pressure drop as well as raising the overall heat transfer. This work considered as a different nanoparticles such as Aluminium oxide (Al2O3), Silicon dioxide (SiO2), Titanium oxide (TiO2) and Zirconium dioxide (ZrO2) to form a nanofluids. This nanofluids possesses high thermal conductivity by using of this increase the heat transfer rate in shell and tube heat exchanger. The selected nanofluids are compared to base fluid based on the thermophysical properties as well as heat transfer characteristics. All the heat transfer characteristics are improved by applying of nanofluids particularly higher results are obtained with using of TiO2 and Al2O3 compared to SiO2 and ZrO2. Mixing of nanoparticles increased in terms of volume percentage it will be increases the all Heat transfer characteristics as well as performance of the heat exchanger.
