摘要

采用多孔介质模型对ASPEN软件设计的高压多组分合成气换热器进行了三维数值模拟

分析了不同的几何结构对壳程流体的传热和压降的影响规律。分析结果表明

采用ASPEN软件设计的换热器具有较好的流动和换热特性;多孔介质模型可用于模拟净燃气过热器壳程流体的流动和换热;在其它参数不变情况下换热器折流板的圆缺度由20%减至15%对壳程流体的换热影响不大

但增加了壳程流体的压降。

Abstract

The porous media model was employed to conduct three-dimensional numerical simulation on a high pressure multi-component syngas heat exchanger designed by ASPEN software.The effect of different geometric structures on heat transfer and pressure drop of shell side fluid was investigated.The results showed that

the heat exchanger designed by the ASPEN software had good flow and heat transfer performance;the temperature distribution of the high pressure multi-component syngas at shell side obtained by the porous medium model agreed well with that designed by the ASPEN software;keeping the other parameters as constants and decreasing the segmental orifice degree of the baffle plate in heat exchanger from 20% to 15%had little effect on heat transfer behavior of the shell side fluid

but the pressure drop was increased.
