Abstract

Fluid flow analysis using structured moving boundary fitted grids is presented. This type of method can be applied to certain moving boundary problems. The Cartesian velocity components are made the primary variables, and grid motion and geometric conservation are handled in a natural way through the contravariant velocities and the Jacobian evaluations. A SIMPLE-based sequential solver along with a staggered grid is employed. Furthermore, appropriate treatments of the discretized form of the diffusion term on a nonorthogonal skewed grid are also discussed. The moving grid approach is applied to simulate test problems involving phase change.
