摘要：

This paper presents a particle-grid superposition method for solving the Navier-Stokes equations. Starting from a deterministic vortex method, the idea is to superpose a finite difference method where large distortions of the particle distribution occur. A matching between both methods is proposed which eventually leads to a domain decomposition strategy that makes it possible to simulate viscous flows at high Reynolds numbers with a limited number of points. Numerical illustrations of the method are given for flows past a cylinder at Reynolds numbers of 3000 and 9500. © 1990.
