Abstract
This paper presents a high fidelity, multi-scale thermal response models for a multiphase syntactic foam as a candidate Thermal Protection System (TPS) material, similar to AVCOAT. Scale-bridging molecular dynamics (MD) simulations are used to characterize the ablation chemistry and to obtain the thermal recession rate. The latter is used in Direct Simulation Monte Carlo (DSMC) simulations to model gas transport, heat transfer, and TPS material recession at the meso-scale level utilizing a strategy to loosely couple DSMC with the thermal response of the syntactic foam. The effect of interstitial void fraction on the steady state temperature profile of the material structure is explored.
