### Abstract

We present an effective method for computing accurate solutions to time-dependent incompressible fluid-flow problems. The method uses an approximate projection method coupled with high-order Godunov convection, and a Crank-Nicholson method for diffusive terms. Linear systems of equations are computed with a multigrid algorithm. The algorithm is demonstrated for incompressible, Boussinesq, and incompressible variable density flows. This algorithm does particularly well at computing high Reynolds number, and inviscid flows as well as those with discontinuous data. We
