The result of numerical simulation of a flat channel with a back-facing step in the presence of tabs by the RANS method is presented. The Reynolds number, calculated by the step height and the average flow rate velocity, was Re = 5000. The data obtained made it possible to analyze the dynamics of interaction between the separated flow behind a tab and the region of the main separation behind a step. Tabs have the greatest influence on the area in close proximity to the step.

通过选项卡控制背面步骤后面的分离流

给出了通过RANS方法在存在标签的情况下对具有背面台阶的平面通道进行数值模拟的结果。由台阶高度和平均流速计算得出的雷诺数为 Re = 5000。获得的数据使我们有可能分析一个标签后面的分离流与一个台阶后面的主要分离区域之间的相互作用动力学. 标签对靠近台阶的区域影响最大。
