Numerical modeling of high-speed rarefied gas flows over blunt bodies using model kinetic equations

The paper is devoted to the development of the numerical approaches to solve model kinetic equations as applied to computing high-speed rarefied gas flows over three-dimensional geometries. The use of a very non-uniform unstructured velocity mesh is proposed, and the influence of the velocity mesh resolution is studied in detail. The test problems include a simple flow over a planar circular cylinder and a three-dimensional flow over a model winged re-entry vehicle.
