Taylor Couette Instability -- CFD Online Discussion Forums

CFD Guest Posts: n/a	I have been trying to get my canned finite volume code simulate the Taylor Couette Instability. This occurs when the flow between 2 rotating cylinders goes unstable after a certain value of the Taylor number is reached. Basically if the outer cylinder is rotating slower than the inner one by a certain ratio, the flow should go unstable. This is often cited as the best validation of a code. Does anyone have experience doing this? At what Taylor numbers could they achieve the instability? How long did it persist? What were the sizes of the cells?
