FINITE-VOLUME ANALYSIS OF SPIRAL MOTION IN A RECTANGULAR LID-DRIVEN CAVITY

With the purpose of providing physical insight into the developing spa nwise flow motion and identifying the presence of Taylor-Gortler-like vortices, we conducted a flow simulation in a rectangular cavity defin ed by a square cross-section and a spanwise aspect ratio of 3:1. The g overning equations were solved for the transient processes by using a finite volume method in conjunction with segregated solution procedure s. In the present work, attention is placed on the spiralling corner v ortices near the two end walls and the longitudinal meandering Taylor- Gortler-like vortices. The investigated Reynolds number is taken to be 1500. As a vehicle for the present flow simulation, validation agains t analytic data was carried out first for a configuration similar to t he problem of interest. This study demonstrates the feasibility of the employed computer code.
