Plane Couette flow: a numerical experimentThe next two animations show a flow close to experimental conditions. You will see that the flow exhibits unstable but recurrent structures. This is the physics we need to explain: how do we identify these structures? And how are they related? In all simulations presented here the Reynolds number is 400, chosen so that the wall-wall separation fits approximately the diameter of the numerically (and experimentally) observed unsteady streamwise rolls. | |
