The aerodynamics of an reentry capsule, Orion Crew Module, during its high altitude reentry from the Earth’s orbit are studied using numerical simulations. The conditions are similar to those that the Orion Crew Module would face when coming back from space missions. The simulations are performed for non-reacting rarefied gas flows which cover the range of hypersonic flow regimes from free molecular to slip flow (Knudsen numbers from 111 to 0.0263). The simulations are done with Direct Simulation Monte Carlo code from hyStrath, the open-source OpenFOAM solvers for hypersonic/rarefied gas dynamics developed by Casseau, et al. The aerodynamics forces and moments are shown to depend on the degree of incidence angle and rarefaction. The results agree well with DS3V code results from Moss, et al. with relatively small errors.
