| Abstract: | In the paper, two-dimension mathematical model and corresponding difference scheme of heat transfer in crossflow tube-to-tube heat exchanger are presented. By comparision with experimental data and performance calculation, it has been proved that the numerical method is effective and feasible. It is a success that the compiled computer program have been used for predicting operation of composed engine air-precooled heat exchanger. |
