The present study discusses the construction of an algorithm for calculating slot suction sockets under conditions of an oncoming flow using discrete vortices. It also presents the effects of flow patterns at different ratios of the oncoming and suction airflow velocities. The dependence of the sizes of the vortex zones arising at the inlet to the suction sockets on the velocity of the oncoming flow, length, and angle of inclination of the socket is determined. Equations are obtained for the critical velocity of the oncoming flow, at which the flow separation mode for the vortex zone 1 changes from separation inside the socket to outside it. The results obtained can be used to design local suction systems profiled according to the outlines of vortex zones.

本研究讨论了使用离散涡流在迎面流动的条件下计算槽吸入口的算法的构建。它还呈现了不同迎面气流速度和吸入气流速度比率下的流动模式的影响。确定在抽吸承口的入口处产生的涡流区域的尺寸对迎面而来的流的速度、长度和承口的倾斜角度的依赖性。获得了迎面流动的临界速度的方程，在该速度下，涡流区1的流动分离模式从插座内部的分离变为插座外部的分离。获得的结果可用于根据涡流区域的轮廓设计局部抽吸系统。
