Abstract

A two dimensional staggered unstructured discretisation scheme for the solution of fluid flow
problems has been developed. This scheme stores and solves the velocity vector resolutes normal and parallel
to each cell face and other scalar variables (pressure, temperature) are stored at cell centres. The coupled
momentum; continuity and energy equations are solved, using the well known pressure correction algorithm
SIMPLE. The method is tested for accuracy and convergence behaviour against standard cell-centre solutions
in a number of benchmark problems: The Lid-Driven Cavity, Natural Convection in a Cavity and the Melting
of Gallium in a rectangular domain.
