摘    要:对于折流板式换热器,壳体中折流板一方面增强了壳程流体的扰动,强化了流体的对流换热,另一方面不可避免地加大了流体的流动阻力,同时会产生流动死区、漏流等不良现象.轴流型管壳式换热器由于壳体中无折流板,因而不存在流动死区等不良现象,壳程阻力损失明显降低.轴流型换热器的传热效果虽因无折流板对流体的扰动而有所降低,

关 键 词:轴流型换热器  阻力系数  Lebesgue测度

Abstract:The flow resistance of the inlet section of heat exchanger with longitudinal flow in shell side was studied with the distributed fluid flow method. Transverse velocity and longitudinal velocity were investigated, and the resistance coefficient of transverse flow was analyzed as well. Prediction was made for the flow resistance of inlet section based on a number of experiments and the corresponding equation was obtained. The deviation of the calculated results with the equation from the experiment data was less than 5 %.
Keywords:longitudinal heat exchanger  flow resistance  Lebesgue measure
