Abstract

Adequate resolution of the flow field is vital to ensure that simulations are sufficiently spatially converged. However, a too finely resolved mesh can lead to excessive computational times. Adaptive Mesh Refinement (AMR) algorithms are able to balance these two constraints by increasing the resolution only where it is needed. In this work, a block-Structured Adaptive Mesh Refinement (SAMR) solver has been coupled to the Mutation++ thermochemical library to enable high resolution simulations of flows in thermochemical nonequilibrium. The solver has been verified using the Method of Manufactured Solutions and computations of hypersonic flows are presented, demonstrating the thermochemical model and the ability of AMR algorithms to resolve flow features.
