The partial admission control stage of a 200 MW steam turbine is studied using CFD and a 3D full-geometry model. The first part of the paper is devoted to the operation of the turbine at nominal load conditions when three (out of four) control valves are fully open, the forth valve is partly open. The circumferential non-uniformity of flow patterns and rotor blade forces are calculated and discussed.
