Thermal and Chemical Non-equilibrium Simulation of A Reentry Vehicle
This paper deals with aerothermodynamic analysis of a Crew Rescue Vehicle (CRV). Space activities of near term call for a new kind of manned space transportation vehicle. Today, the capsule technology is still the safest and cheapest way to get into orbit and return back to Earth, especially for manned space exploration missions to Moon and Mars. The design of these systems demands a great effort to understand the many implications of the extreme loading conditions that they have to withstand. To this end, in this work computational fluid dynamic analyses were performed to simulate the flowfield and forebody heating environment about an Apollo-like vehicle re-entering, in particular, by LEO orbit. The air is modeled as a reacting gas mixture with thermal and chemical nonequilibrium. Three-dimensional Navier-Stokes simulations are computed at the peak heating conditions of the re-entry trajectory to study the effect of chemical and thermal non-equilibrium on the vehicle heatshield by considering alternatively its surface as a non catalytic wall. The role played by surface catalysis on the heatshield thermal loading is not considered.
