摘要
建立并导出叉流管－管型换热器传热过程的二维数学模型及相应的差分格式。对比实验数据和性能计算结果，表明数值方法是有效可行的，据此编制的计算机程序已成功地用于组合发动机空气预冷换热器工作过程的预测。
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.
