Discrete vortex analysis of unsteady flow about two-dimensional cambered plates
Technical Report

OSTI ID:5520899
The evolution of a two-dimensional, incompressible, rapidly decelerating, time-dependent viscous flow about three cambered plates with included angles of 120, 180, and 240 degrees is simulated through the use of the discrete vortex model. Vorticity is represented by a distribution of discrete vortices. Each vortex is convected in the velocity field, calculated locally using the Biot-Savart law. The roll-up of the vortex sheets, the distribution of velocity and pressure on the cambers, and the drag force are calculated at suitable time intervals for a prescribed time-dependent flow. The results are compared with those obtained experimentally. 59 figs.
