A Discrete-Vortex Analysis of Unsteady Flow About Cambered Plates

Abstract

The evolution of a two-dimensional, incompressible, rapidly decelerating, viscous flow about a sharp-edged camber is simulated through the use of discrete-vortex method. An extensive study of the velocity field in the vicinity of the singular points led to the development of a novel method for the introduction of vorticity. The roll-up of the vortex sheets, the distribution of velocity and the pressure on the camber, and the drag force are calculated and compared with experiments.
