The correctness of using periodic unit duct model to simulate the shell-side flow and heat transfer is confirmed for the first time, when using the corrugated tube.
本文首次验证了纵流壳程换热器选用波纹管作为换热元件采用单元流道模型对壳程进行数值模拟的正确性，同时验证了数值模拟结果的正确性。
Under low packing density, convection is significant in shell-side flow, which is preferable for the reduction of dead zone area and the higher utilization of contacting area.
较低的封装分率下，组件壳程对流作用明显，有利于减少死区，充分利用膜接触面积。
