摘要

本研究讨论了在迎面气流条件下利用离散涡流计算槽吸口的算法结构。本研究还介绍了来流和吸入气流速度不同比率下的流动模式的影响。研究还确定了在吸入口产生的涡流区的大小与来流速度、长度和吸入口倾角的关系。得出了来流的临界速度方程，在该临界速度下，涡流区 1 的流动分离模式从插座内分离变为插座外分离。所得结果可用于根据涡流区的轮廓设计局部抽吸系统。

Determination of the Influence of the Oncoming Flow on the Vortex Zones at the Inlet to the Suction Sockets. Part 1. Flat Problem

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.
