Elliptic-Vortex Method for Incompressible Flow at High Reynolds Number
Abstract
An elliptic-vortex model for approximating the time-dependent Navier-Stokes equations at high Reynolds number is presented. One attractive feature of the new method is that the elliptic-computational elements used in this model are very good for boundary layer flow. Also introduced are a modified boundary algorithm and a new outflow boundary condition. Numerical computations for flat-plate problems show that the new method converges very fast and the numerical results are in excellent agreement with known facts.
