This article presents a numerical method for determining correlation to predict the air-side heat transfer coefficient and friction factors as a function of the Reynolds number and geometric variables of the heat exchanger. The air-side heat transfer coefficients are determined from the condition that the calculated and measured outlet temperatures of the cooling liquid are equal. The presented method for thermal analysis of heat exchangers is based on the finite volume method. A nonlinear regression technique is used to correlate 18 sets of the automotive radiator data to develop the heat transfer and friction correlations. Two correlations for the air-side Nusselt number are presented. The first correlation is derived from experimental measurements, whereas the second one is based on the CFD simulation of 3D laminar flow in the heat exchanger. The empirical correlation gives smaller values of the Nusselt number. The maximum relative difference between the empirical correlation and the numerical results is about 16%.
