Modeling of flow through porous media using hybrid MPI-CUDA parallelization strategies using DSMC

Usage Details

Our target problem involves modeling and simulation of chemically reacting flows through porous microstructures of thermal protection system (TPS) materials. Such materials are designed to protect the space vehicle and its crew from the aerothermodynamic heating during reentry into the Earth’s atmosphere. Candidate TPS materials such as Phenolic Impregnated Carbon Fibers form a complex network of carbon fibers at the micrometer length scale. In order to quantify the properties and performance of the TPS, we have developed a CUDA-based Hybrid Approach for Octree Simulations (CHAOS) DSMC solver that can accurately predict the heat transfer of the boundary layer gases to the material.
