泡状管换热器强化传热与整体性能的数值模拟
Numerical simulation on heat transfer enhancement and performance of heat exchanger with bubbly pipe
摘要
Abstract
Considering the coupled heat transfer between tube pass and shell pass,a numerical simulation of a whole tube-and-shell heat exchanger with bubbly pipe was carried out by using commercial codes of Fluent.The simulation results were compared with those of smooth pipe heat exchanger with same structure and surface area. The heat transfer enhancement and factors of pressure drop difference were discussed by comparing the results of the two kinds of heat exchanger.And the bubbly pipe heat exchanger performance was also reviewed.The results reveal that bubbly pipe can remarkably enhance the heat transfer on both side of the tube,and the overall heat transfer coefficient increases significantly than that of smooth pipe.The tube side pressure drop of bubbly pipe heat exchanger is higher than that of smooth pipe heat exchanger,but shell side pressure drop is lower.The performance evaluation criteria (PEC)show that bubbly pipe can improve the heat transfer performance in shell pass than smooth pipe.关键词
