Abstract
A one-dimensional material response implicit solver with surface ablation and pyrolysis is implicitly coupled to LeMANS, a CFD code for the simulation of weakly ionized hypersonic flows in thermo-chemical non-equilibrium. Following verification and validation of the blowing wall boundary conditions and ablation coupling, the implementation of a moving mesh algorithm in the flow solver is proposed. A set of simple test-cases is presented, proving that the method used preserves the fluxes. Using the well defined case of the IRV-2 vehicle, the implicit coupling method is tested over a re-entry trajectory.
