管板流固热耦合分析及优化设计

Fluid-Solid-Heat Coupling Analysis and Optimization Design of Tube-Sheet

选用60 mm厚管板流固热耦合模型,计算60 mm厚管箱的3种载荷工况,即单独施加由流固热耦合计算出的温度载荷、单独施加由流固热耦合计算出的压力载荷、同时施加由流固热耦合计算出的温度载荷和压力载荷。并对管板厚度进行改变,做出不同管板厚度下的强度分析,得到当管板厚度为47.5 mm时,为最优化的选择。

The fluid-solid-thermal coupling model of tube sheet with 60 mm thick was selected to calculate the three load conditions of 60 mm thick tube box, namely, the temperature load calculated by the fluid-solid thermal coupling was applied separately, the pressure calculated by the fluid-solid thermal coupling was separately applied,and the temperature load and pressure load calculated by fluid-solid-heat coupling were applied at the same time. The thickness of the tube sheet was changed, and the strength analysis under different tube sheet thicknesses was carried out. The results showed that optimal tube sheet thickness was 47.5 mm.
