Abstract
Local time stepping (LTS) and adaptive mesh refinement (AMR) have been implemented into rhoCentralFoam, a compressible solver within the open source computational fluid dynamics (CFD) code OpenFOAM. The LTS solver has been validated using a compressible Couette channel with heat transfer and a supersonic at plate. An excellent concurrence is found for these cases in comparison with the solutions with the obtained results being, respectively, 2.56 and 8.96 times faster compared to the unmodified solver. The AMR solver was employed to simulate hypersonic flow over a 30° wedge, and the Sod shock tube test case, and has also achieved satisfactory agreement with the analytical solutions. These results highlight the potentially significant computational cost savings that may be achieved when solving high-speed, compressible flows using this approach.
