CFD STUDY OF THE AIR FLOW AND HEAT TRANSFER IN A LOUVERED FINNED HEAT EXCHANGER FOR VEHICLES

The air fl ow and the heat transfer in louver fi ns were simulated using the CFD method. The results of the CFD calculations on the air pressure drop in the air fl ow and on its outlet temperature were compared with the experimental data, obtained for the air velocities 1.5, 2.5, 3.5, and 4.5 m/s. In all these cases, the errors in determining the pressure drop in the air fl ow and in its outlet temperature were within 10%. The infl uence of the louver angle, the fi n pitch, and the louver pitch on the rate of heat transfer in the air fl ow and on the pressure drop in it were investigated.
