Vorticity Distributions in Unsteady Flow Separation
Abstract
Computational analysis and results are reported for three problems. (1) Development of a laminar boundary layer on both the windward and leeward sides of a plate which is moved impulsively normal to its plane. The model of inviscid flow outside the boundary layer includes a moving and intensifying line vortex, which approximates the vortex spiral cast off from the edge of the plate. (2) Mutually-induced movement and interdiffusion of counter-rotating viscous line vortices, simulated by the random-vortex method. (3) Development of flow separation on a slender elliptical cylinder, which is impulsively set into rotation around its central axis, also simulated by the random-vortex method. Unsteady boundary layers; Random vortex method.
