The results are presented here of a piece of experimental research, the aim of which was to find the most suitable shapes of all parts of the double-flow design of the exhaust hood in a steam turbine. Various forms of the walls of the casing and their influence upon the loss coefficient are described. Attention was paid to the process of blowing the steam into the boundary layer on the wall of the diffuser and stating the overall loss. The computations of the flow in the diffuser proper are presented and the influence of the density of the grid and the influence of the rotation of flow are shown. The actual inlet flow parameters are taken into consideration.
