Investigation of Heat Transfer Efficiency for the Available Heat Engine Fluids in Libya

Abstract

Heat transfer has a variety application throughout our life, cars one of these touchable applications as are used every single day and especially the fluids for cooling car engines. In this research, the heat transfer efficiency of thermal motor fluids has been studied by conducting some laboratory experiments for four types of fluids that used in the cooling of motor engines available in the Libyan markets and studying some physical properties that affect the rate of heat transfer and calculate the total heat transfer coefficient for each type of the water, compared with each other, calculating the density of each sample of water, as well as the viscosity of each sample.
