【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%.更多还原
