Abstract

This study explains an experimental and theoretical result of an automotive heat exchanger, car radiator. A car radiator model is designed and fabricated using three different approaches. First one is by using transparent plastic tubes to observe the water flow characteristic. This study used dye as a reference that represents heat and velocity characteristic. Second, study on a prototype of square radiator using similar materials as the real one. At the end of the study, an analysis is made by comparing the average value of overall heat transfer coefficient. Third, conduct a simple software analysis using CFD approach involving FLUENT and GAMBIT interface. Later, these three experimental data is gathered and analyzed. At the end of this study, predicted result such as outlet temperature for both water and air, radiator effectiveness and heat transfer performance is achieved.
