| Abstract:
In this Study, radiator performance for passenger car has been studied experimentally in a wide range of operating conditions. Experimental prediction of Nusselt number and heat transfer coefficient for coolants in radiator tubes are also performed with e-NTU method. The total effectiveness coefficient of radiator and heat transfer coefficient in air side is calculated via trial and error method considering experimental data. The Colburn factor and pressure drop are also estimated for this heat exchanger. Examples of application demonstrate the practical usefulness of this method to provide empirical data which can be used during the design stage.
