Unsteady separation phenomena in a two-dimensional cavity
Abstract
The investigation makes use of the full momentum equation. A two-dimensional oscillatory cavity flow is considered. The results are compared to the steady case with only one fixed separation streamline along the line of symmetry. An illustration is given of a dynamic pattern of separation and reattachment. The numerical approximate solutions for the full momentum equation show that separation is regular when transverse pressure gradients are included in the theory.
