Turbulent flow simulations are presented in this paper. A 3-D finite difference numerical code, written for general, curvilinear, body-conforming coordinate systems, is used. Simulations of turbulent flows over a flat plate are compared to theoretical results in order to assess the correctness of the implementation of the formulation. Transonic turbulent flows are then simulated about the Brazilian Satellite Launch Vehicle (VLS) configuration, currently under development at IAE. Two eddy viscosity turbulence models are chosen for this numerical method, considering single- and two-equation closures. These two models were natively developed for aerospace applications. In general, good results within engineering error margins are obtained with the method presented here. Keywords. CFD, Turbulent flow, Aerospace configuration.
