摘要
在换热器的传热性能试验中 ,对流换热系数的测定是一个重要的组成部分。对于板式换热器而言 ,用等雷诺数法来获得其对流换热系数是比较合适的一种方法 ,但对试验过程的控制要求比较高。文中阐述了一种修正的等雷诺数方法——等流速法 ,它使试验过程的控制十分方便。通过实例 ,介绍了该方法的具体应用。表 2参
The determination of convection heat exchange factors constitutes a major element in the heat transfer performance test of heat exchangers. So far as plate heat exchangers are concerned, Equal Reynolds Number Method can be considered as a fairly appropriate one. However, there is a little difficulty in the application of the Method. The present paper describes a modified Method Equal Velocity Method. The control of test process is more convenience with the modified Method. Detailed uses of the modified Method are introduced through an instance. Tables 2 and refs 4.
