Title: A Multi Block Flow Solver for Viscous Compressible Flows
Abstract: A 2 dimensional Compressible Navier Stokes flow solver has been developed. The Navier Stokes equations are discretized in space following the method of Jameson using central differencing in space with added artificial dissipation. For the computation of the viscous fluxes, gradients of the velocities and temperature are evaluated using the gradient theorem on auxiliary cells. The resulting system of ODE’s is integrated in time using the explicit Runge Kutta procedure. To facilitate the grid generation for complex geometries and to permit an efficient use of parallel computers a multi block structure has been adopted yielding the possibility to split the computational domain into multiple patched blocks. The code was validated comparing calculated results for the flow over a flat plate with Blasius theory, and comparing the results for the flow around a NACA 0012 profile with other computations. Comparing single and multi block computations showed that the multi block structure does not affect the convergence of the numerical procedure or the calculated results.
