摘要

This paper presents a pressure-based flow solver of implementation on unstructured meshes. The scheme is developed from a straightforward pressure correction method and is based on an explicit, spatially centred, non-staggered, cell-vertex store finite volume method. Runge-Kutta time integration is employed. The scheme is applicable to incompressible and compressible flows and so greatly increases the range of flows accessible to the unstructured finite volume methopd. Solutions are presented for simple inviscid channel flows for Mach numbers from zero to 5, demonstrating the Mach number range that can be treated. Viscous solutions for both incompressible and compressible turbulent flows are presented. They show encouraging agreement with experimental measurements.
