摘要: 采用对管外流体温度进行加权平均的方法 ,应用 Laplace变换和归纳法 ,对任意 n排单程叉流翅片管束式换热器的换热和温度分布进行了分析。得到了管内 ,管外流体的温度分布和换热器效率的简洁表达式。Abstract: Using the method of weighted mean value of outside fluid temperature along with the Laplace transformation and recursive procedure,an analysis of the heat transfer and temperature fields of one pass finned tube bundle cross-flow heat exchanger has been carried out.The spatial distributions of the fluid temperature fields inside and outside the tubes are presented.It is shown that for such flow arrangement,the relation for heat exchanger effectiveness has a simple explicit form.
