In this paper, we extend the use of automatic rezoning to viscous flow in two dimensions. In a previous paper, we tested this technique on inviscid flow, with very good results. To simulate viscosity, we follow Fishelov's idea of explicitly taking the Laplacian of the cutoff function, but unlike Fis

A numerical scheme has been obtained rigorously from the initial-boundary value problem for the NavierΒ± Stokes (NS) equations in the context of the vortex method. The technique is based on a transformation of the NS equation into a parabolic equation which has an exact solution. The numerical scheme
The relation between the lattice Boltzmann method, which has recently become popular, and the kinetic schemes, which are routinely used in computational fluid dynamics, is explored. A new discrete velocity method for the numerical solution of Navier-Stokes equations for incompressible fluid flow is
A complete boundary integral formulation for incompressible Navier -Stokes equations with time discretization by operator splitting is developed using the fundamental solutions of the Helmholtz operator equation with different order. The numerical results for the lift and the drag hysteresis associa
This paper considers the accuracy of projection method approximations to the initial-boundary-value problem for the incompressible Navier-Stokes equations. The issue of how to correctly specify numerical boundary conditions for these methods has been outstanding since the birth of the second-order m
