利用ANSYS参数化建模方法建立了管壳式换热器的参数化模型,在ANSYS FLUENT中对管壳式换热器壳程流体的流动与传热进行了数值模拟计算,得到换热器壳程流体温度场、速度场和压力场;分析了折流板间距及弦高对换热效率和壳程流体压降的影响,对于设计传热效率高、流体阻力小的换热器进行了有益探索。

A parametric model on the shell and tube heat exchanger is established by using ANSYS parametric modeling method. The numerical simulation on the shell-side fluid flow and heat transfer of shell and tube heat exchanger is performed on ANSYS FLUENT, and Shell-side fluid temperature field, velocity field and pressure field are acquired;and the effects of the baffle plate spacing and string height of heat exchanger to the heat transfer efficiency and shell side fluid pressure drop is analyzed. It is a beneficial exploration to the design to high heat transfer efficiency and low fluid resistance of the heat exchanger.
