摘要

对帘式折流片换热器壳程流体流动死区大小及分布规律进行了数值模拟和实验研究。研究表明，帘式折流片换热器壳程流体流动死区大小随着Re的增加而降低；流动死区的大小和分布规律受折流栅装配方式的影响，折流栅同向装配时壳程死区小于折流栅对称装配，当壳程Re分别为5000、10000和15000时，折流栅同向装配时的帘式折流片换热器壳程死区分别为折流栅对称装配时的50.5%、51.6%、43.0%。

Abstract

The size and distribution regularities of flow dead zone of shutter baffle heat exchanger were researched by numerical simulation and experiment. It is concluded that the size of flow dead zone in shell side of shutter baffle heat exchanger is reduced with increase of Reynolds number. The size and distribution of flow dead zone are affected by assemble types of shutter baffles. When the shutter baffle is co-rotating arranged

the size of dead zone in shell side was less than that of symmetrical. When Re=5000

Re=10000 and Re=15000

the dead zone in shell side of shutter baffle heat exchanger with shutter baffle co-rotating arrangement are respectively 50.5%、51.6%、43.0% of that with shutter baffle symmetrical arrangement.
