Abstract: Three-dimensional numerical simulation for shell side turbulent flow and heat transfer characteristics in baffle-plate heat exchangers was conducted with a commercial software—FLUENT，through which the static temperature field，velocity vector field，particle line field and static pressure drop field were obtained. Based on the numerical simulation results，the mechanism in the shell side turbulent flow and heat transfer was investigated from different aspects.

摘要： 利用FLUENT软件对折流板换热器壳程湍流流动与换热进行了三维数值模拟。得到了折流板换热器的温度场、速度场、质点迹线图、压降分布图等。根据模拟得到的结果，从多个方面对折流板换热器壳程湍流流动与强化传热进行了有益的探讨。
