Further Information
An investigation of some form of preconditioning approach for the incompressible Navier-Stokes equations is presented. We have implemented preconditioning in conjunction with a high-resolution (characteristics-based) scheme for the advective terms, a non-linear multigrid algorithm and an explicit fourth-order, total variation diminishing (TVD) Runge-Kutta scheme. Computations have been carried out for flows through suddenly-expanded and expanded-contracted geometries, for a broad range of Reynolds numbers, featuring flow separation as well as instabilities.
