Description
  • We work with the system of equations describing non-stationary inviscid compressible fluid flow in 3D, i.e. the Renolds-Averaged Navier-Stokes (RANS) equations, and we focus on the numerical solution of these equations and on the boundary conditions. In particular, we choose the implicit finite volume method, and the two-equation turbulent model $k-w$ (Kok), see \cite{Kok}. We use the analysis of the Riemann problem for the construction of the boundary conditions in order to match the experimental data. As a part of this work we present own-developed software for the solution of the 3D RANS equations, using the shown implicit method.
