Abstract
Modelling the interactions between porous flow and pure flow at atmospheric entry conditions is a challenging task. New models and high fidelity numerical tools are required to better understand porous material and aerothermal flow interactions for ablation problems at different flow regimes. Volume Averaged Navier-Stokes equations (VANS) are applied to develop a universal solver (KATS-US) that solves both porous and flow domains at the same time. Numerical testing and verification is carried out through two benchmark channel flow problems. Additionally, a set of simulations of a permeable arc-jet test sample is carried out under supersonic and hypersonic flow conditions in order to study high velocity flow through porous materials. A qualitative assessment of shock formation, porous flow development, pressure change across the porous sample and temperature evolution throughout the porous domain is studied. An ablative test case is studied under high velocity flow to assess the ablation model capability of the newly developed tool. Moreover, the numerical tool is used to model HyMETS test case and the predictions are compared for FiberForm® test sample.
