Flow Between a Solid Wall and a Rotating Disc with Pressure Relief Holes
The report demonstrates the application of the PHOENICS code to analysis of the flow between rotor discs and solid walls in turbomachinery, with special emphasis on the effect of flow through pressure relief holes in the disc. The analysis involves full 3D solution of the momentum equations in an angular interval surrounding a pressure relief hole with cyclic boundary conditions in the circumferential direction. The variable settings in the satellite programme and the GROUND-station are described and typical results are presented and discussed.
