Implementation of density-based solver for all speeds in the framework of OpenFOAM

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract In the framework of open source CFD code OpenFOAM, a density-based solver for all speeds flow field is developed. In this solver the preconditioned all speeds AUSM+(P) scheme is adopted and the dual time scheme is implemented to complete the unsteady process. Parallel computation could be implemented to accelerate the solving process. Different interface reconstruction algorithms are implemented, and their accuracy with respect to convection is compared. Three benchmark tests of lid-driven ca... Title of program: allSpeedUnsteadFoam/ allSpeedUnsteadFoam_dualtime Catalogue Id: AETK_v1_0 Nature of problem This software provides a library of models for the simulation of steady and unsteady all speeds flow field (all Mach number flow field including incompressible and compressible flow). Combining this library with other libraries within OpenFOAM, such as turbulence, radiation, solid conduction, etc., the more complex multi-physics model including all speeds flow field could be established conveniently.
