第三类边界条件下管内对流换热实验方法研究

EXPERIMENTATION OF FORCED CONVECTION HEAT TRANSFER IN TUBES UNDER THE THIRD BOUNDARY CONDITION

典型的管内对流换热实验均在第一、第二类边界条件下进行。本文研究了第三类边界条件下，实验装置的设计、实验数据的计算整理方法并给出了实验实例。本实验装置简单，实验参数易测并且实验关联式更易于工程应用。

Typical experiment of convection heat transfer in tubes is under the first or the second boundary condition.This papar is about forced convection heat transfer in tubes under the third boundary condition,and gives the design of experimental equipment,the method of calculating and the example of the experiment.This experimental equipment is simple,experimental parameter can be determined easily and the dimensionless equations are more suitable for engineering applications.
