摘要:
利用CFD分析软件Fluent分别建立了安装角度为30°、45°、60°3种扇叶型折流板换热器周期性模型，对不同的流态进行数值模拟计算，研究了折流板安装角对扇叶型折流板换热器性能的影响。结果显示：壳程流体在折流板引导下呈斜向流动，斜向流动能够有效抑制流体诱导振动；筒体附近流体流速较高，中心区域流速较低；不同流态下，随着安装角增大，换热器壳程压降降低，综合性能增高。安装角30°时换热器传热系数大于另外两者。
Abstract:
Three periodic models with different installation angles of the blade baffle heat exchanger were established by the CFD analysis software Fluent. The installion angles were 30°, 45°, 60°, respectively. And the performance of heat exchanger with different installation angles was investigated. Results showed that in the diversion of the baffle, the shell-side flow became sideling flow, which could restrain the flow induced vibration effectively. The velocity of the fluid in the near wall region was higher than that of the central region. With the increase of the installation angle, the shell-side pressure drop decreased, the comprehensive performance of the heat transfer coefficient of the exchanger increased. When the installation angle was 30° the heat transfer coefficient was larger than the other two.
