Parallelization of Unsteady Adaptive Mesh Renement for Unstructured Navier-Stokes Solvers.

摘要

This paper explores the implementation of the MPI parallelization in a Navier-Stokes solver using adaptive mesh renement. Viscous and inviscid test problems are considered for the purpose of benchmarking, as are implicit and explicit time advancement methods. The main test problem for comparison includes effect from boundary layers and other viscous features and requires a large number of grid points for accurate computation. Experimental validation against double cone experiments in hypersonic ow are shown. The adaptive mesh renement shows promise for a staple test problem in the hypersonic community. Extension to more advanced techniques for more complicated flows is described.
