Abstract : The main accomplishments under this effort include development of numerical algorithms for solving the Navier Stokes equations with higher order spatial discretizations, a generalized thermo-chemical model, and a one equation turbulence model on unstructured meshes. This report focuses attention on the implementation of the thermo-chemical modeling, viscous fluxes, turbulence modeling, and higher order spatial discretizations. Solutions are presented for an equilibrium air nozzle, RAM 11-C reentry probe, Aeroassist Flight Experiment, an analytic forebody, and the turbulent flow over a flat plate. (AN)
