| 摘 要： | 通过FLUENT计算流体力学软件对旋流板塔内的气相流场进行数值模拟分析。采用k-ε湍流模型和SIMPLER算法，对旋流板塔内气相流场进行三阶运算，得到气相流场的三维描述。模拟结果表明：将模拟所得的压降与试验值进行对比，发现在小进气量工况下数值模拟结果和试验结果吻合较好；在旋流板塔流场内部，存在一轴向速度为负的区域；切向速度随着高度的增加而强度减弱；径向速度随着高度的增加，减小的趋势比较明显。

| Abstract: | The gas flow field on rotating stream tray was studied by using FLUENT CFD software. By the k-ε gas turbulence model and SIMPLER algorithm，a 3-D gas flow field on rotating stream tray has been obtained by third-order calculation. The numerical results agree well with experiment data at small inlet flow rates. A negative-velocity zone is found in gas flow field. As height increases，the tangential velocity decreases，and radial velocity decreases more significantly. |
