摘　　要：在第三类边界条件下，管内强制对流换热实验装置相对较为简单。由于实验避免了对管壁多点温度的直接测量，使实验相对简化。但在实验数据处理时，需利用已有的管外传热实验结果，即外部的传热条件必须是能够计算得到的。此外，本实验结果用于各类管状换热器的设计计算时，管外的介质温度往往是已知的，所以利于推广。Abstract Experimental test rig used for the forced convection in -tube heat transfer is relatively simple under the third kind boundary conditions.The test is simplified by avoiding direct multi point measurement on the tube wall.However,It is required to obtain some outside tube test data to process the experiment results,that is to say,the outside heat transfer conditions have to be calculated out.In addition,due to the known temperature of the outside flow medium,this experimental results are easy to be applied when they are used in the design of different tubular heat exchangers.
