Performance Enhancement of an Automobile Radiator by Using A Nozzle Arrangement

Abstract

Engine cooling system ensures the smooth running of an engine by dissipating heat from engine to environment. When engine is in operating condition, enormous heat is generated. If that heat cannot be dissipated properly, engine efficiency is decreased and furthermore overheating is harmful for the engine. For developing a highly efficient cooling system, researchers have invented many technologies like using nanofluid, designing cooling fan, attaching fin, etc. In this study, emphasis will be given on reducing frontal air temperature of the radiator by using a nozzle arrangement. Due to Joule-Thompson effect, air while passing through the nozzle arrangement, air temperature is reduced. This air will increase the cooling effect of radiator. This concept will be utilized and experimented in this study. And the experimental result is compared with the without nozzle arrangement condition. The percentage of increasing cooling effect is also shown in this paper.
