Study of Heat Transfer and Flow Resistance Performance for an Automobile Strip-Tube Radiator

WU Li-ping , LIN Gui-ping (Beijing University of Aeronautics and Astronautics, Beijing 100083, China)  
In this paper, a mathematical model to predict the performance of heat transfer and flow resistance for automobile strip-tube radiator is established based on the experimental research and analysis computation, namely calculation correlation of the Colburn j-factor and Fanning friction factor, and computation procedures are compiled. The prediction is basically in agreement with the experimental results at the range of conventional working condition. At the same time, Y. J. Chang model is employed and compared with the experimental values on the same conditions. And the influence of the structural parameter on the performance of radiator is analyzed, so that the gist for improving the performance of radiator is provided.
