摘　　要：建立了板式换热器水侧单流道CFD仿真计算模型,并通过与实验点的对比验证了该模型的精确性.基于数值模拟结果,拟合得到板式换热器水侧换热系数和摩擦因子计算关联式,为板式换热器的优化设计提供了依据.A single channel CFD simulation calculation model of a plate heat exchanger is established and the accuracy of the model is verified by comparison with the experimental points. The water side heat transfer coefficient and frictional coefficient calculation correlations of plate heat exchanger are obtained based on the numerical simulation. The correlations provide the basis for the optimization design of plate heat exchanger.
