摘要：

We investigate the vortical flow structure which has evolved in a rectangular cavity defined by a depth-to-width aspect ratio of 1:1 and a span-to-width aspect ratio of 3:1. The vortical system of interest consists of a dominant eddy, secondary motions, and spiraling spanwise motion. The objective of this study was to broaden knowledge of: 1) how the Taylor-Gortler vortices emerge and modify the flow structure; 2) why the left vortex differs from its right counterpart in each unsymmetric pair of TGL vortices. Most importantly, the intent of this study is to discuss the formation of flow instabilities from the energy standpoint.
