Experimental Prediction of Nusselt Number and Coolant Heat Transfer Coefficient in Compact Heat Exchanger Performed with є-NTU Method

Authors
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 􀄰􀀐􀀱􀀷􀀸 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.
