本文研究了板式换热器两交叉波纹通道内的流体力学特性和流体分布。一个三维模型的实际尺寸的几何形状的两个交叉波纹通道提供的人字形板，并考虑到进口和出口端口已进行了数值研究。数值计算结果与实验测量结果进行了验证。讨论了接触点附近的局部流动特性。给出了板式换热器两通道间流体的速度、压力和流量分布。
In this work the hydrodynamic characteristics and distribution of flow in two cross-corrugated channels of plate heat exchangers have been investigated. A three-dimensional model with the real-size geometry of the two cross-corrugated channels provided by chevron plates and taking into account the inlet and outlet ports has been conducted for the numerical study. The numerical results have been validated with the measurements taken by laboratory experiments. The local flow characteristics around the contact points have been discussed. The velocity, pressure and flow distribution of the fluid among the two channels of the plate heat exchanger have also been presented.
