A detailed investigation of the flow in a steady lid-driven cavity of depth to width ratio 1:2 containing a circular cylinder is provided. Three different Reynolds numbers (based on the lid velocity and cavity depth) of 100, 500 and 1000 as well as four different cylinder radii to cavity depth ratios (0.1, 0.2, 0.3 and 0.4) located at three different positions along the horizontal centerline of the cavity, are considered. It appears that these flows can be classified into seven different flow patterns. These flow patterns are given for different cylinder radii and positions as well as Reynolds numbers. There is a tendency that for a given cylinder radius, there are more transitions between different flow patterns for a small radius than for a large radius while for a given Reynolds number, the number of transitions is larger for high Reynolds numbers than for low Reynolds numbers. Overall, a larger number of flow patterns tend to emerge as the Reynolds number increases for small radii. The largest variety of flow patterns occur for the left-sided cylinder due to the interaction with the large anti-clockwise circulation flow formed at the bottom left corner.

提供了在一个深宽比为1：2的，包含圆柱的稳定盖子驱动型腔中的流动的详细研究。三种不同的雷诺数（基于盖速度和腔深度）分别为100、500和1000，以及四个不同的圆柱半径与腔深度之比（0.1、0.2、0.3和0.4）位于沿水平线中心线的三个不同位置腔，被认为。看来这些流可以分为七个不同的流模式。这些流动模式是针对不同的圆柱半径和位置以及雷诺数给出的。对于给定的圆柱半径，存在一种趋势，即对于给定的雷诺数，对于较小的半径，对于较大的半径，在不同的流型之间会有更多的过渡，高雷诺数的跃迁数大于低雷诺数的跃迁数。总体而言，随着雷诺数的增加，小半径会出现大量的流动模式。由于与在左下角形成的大量逆时针循环流的相互作用，左侧圆柱体出现了最多的流型。
