NUMERICAL SIMULATION OF THE TURBULENT COMPRESSIBLE GAS FLOW IN THE VANELESS MACHINES
Kyncl M., Pelant J.
pages 379 - 382, full text

We work with the numerical solution of the turbulent compressible gas flow. We show the numerical simulation of the effect observed in the special vaneless stator-rotor system. The considered axissymmetrical problem is solved numerically. The system of the Reynolds-Averaged Navier-Stokes equations with the k-omega turbulent model is reformulated into the cylindrical coordinates. The finite volume method is used for the solution of the resulting system of equation in meridian planes. At the boundary, the classical Riemann problem is modified to yield physically relevant boundary conditions, with the aim to keep the conservation laws. Suggested procedures were programmed into the own software, and used on examples. The described method can be used for flow simulation in symmetrical channels of arbitrary apparatuses.
