ON END-WALL CORNER VORTICES IN A LID-DRIVEN CAVITY

We conducted a pow simulation to study the laminar flow in a three-dim ensional rectangular cavity. The ratio of cavity depth to width is 1:1 , and the span to width aspect ratio (SAR) is 3:1. The governing equat ions defined on staggered grids were solved in a transient context by using a finite volume method, in conjunction with a segregated solutio n algorithm. Of the most apparent manifestation of three-dimensional c haracteristics, we addressed in this study the formation of corner vor tices and its role in aiding the transport of fluid flows in the prima ry eddy and the secondary eddies.
