Abstract

Direct methods for solving the generalized Boltzmann equation are advanced by simulating flow past three-dimensional immersed bodies in diatomic nitrogen in rotational-translational non-equilibrium. The simulations are performed by solving the entire domain with the generalized Boltzmann equation using a solver based upon the conservative discrete ordinates method of Tcheremissine. Coarse and refined grid solutions are generated for three axisymmetric three-dimensional bodies - blunt body, bicone, and hollow flared cylinder. The solutions are compared and a parallel implementation is developed to enable further levels of grid refinement.
