Flow in the Cross-Over Channel of a Steam Turbine

The document deals with the research of flow in the cross-over channel of the high-pressure stage with partial admission of first stage. In the opening part there is a description of the experimental model and the method of measuring flow fields with high velocity gradient using the stereo PIV principle. The second part describes the design of the model inlet part. The third chapter deals with measuring in the cross-over channel outlet slot with no influence of the stator blade cascade of the following stage. The stator blade cascade feedback is described in the fourth part. During all the measurements we observe the influence of the shaft revolution on the flow field at the cross-over channel outlet.
