Flow Parameters Simulation Technique in Annular Turbine Cascade INLET
Original language description
This article summarizes the concept of equipment which produces the required flow parameters at the inlet of annular turbine cascade. The investigation of inlet flow parameters - the boundary layer on hub and tip inlet channel end-walls and the inlet flow turbulence are part of a project intent on a flow in multistage steam turbine arrangement. This variable inlet can produce the laminar or turbulent boundary layer, respectively the laminar or fully turbulent velocity profile in the inlet channel. The change of inlet turbulence level is controlled by the grid. The detailed measurement of inlet flow: the turbulence and the total pressure distribution across the height of inlet channel were performed by HWA (hot wire anemometry) probe and by total pressure probe, respectively. The measurement results characterize the inlet flow for several inlet channel arrangements and are used for the experimental investigation of the flow field inside the stage and as the inlet parameters for CFD simulations.
