Abstract: Now a day’s in the current domain, manufacturing industries are competing to reduce the cost and fuel consumption rates. Especially, in automobile and aerospace applications because of the improvement of lightweight metal advantages. Magnesium, aluminum and other few materials are considered as lightweight materials to use in required applications due to their inherent properties. Therefore, in this paper tried to characterize the advances of LM20 aluminum alloy rods by using the die-casting processes at various processing temperatures followed by room temperature, 373 K, and 473 K. The main aim is to study the effect of various processing temperature on microstructures and mechanical properties of LM20 alloy. Also, this paper reveals the stability of the microstructures of LM20 aluminum alloy though the processing temperature has been increased. The tensile strength, hardness of the LM20 aluminum alloy was decreased with increase in processing temperature. Similarly, the wear, and sur

Abstract: In this paper, numerical method is developed and simulations of flow and heat transfer of nanofluids is presented. The effect of nanoparticle volume fraction for the enhancement of heat transfer is examined for several sets of values of Reynolds numbers. The study is conducted for pure water and watercopper nanofliud. The study is carried out for Reynolds numbers of 100 and 150 and for volume fraction of nanoparticles of 0, 0.05, 0.10 and 0.15. The mean Nusselt numbers for front and rear cylinders are obtained. The obtained results indicated that the increase of nanoparticles volume fraction has a positive effect on the mean Nusselt number.
