ABSTRACT:
A method and apparatus is provided for improving the performance of vapor turbine diffusers by preventing flow separation from the diffuser walls. Such separation from the diffuser walls is decreased or eliminated herein by chilling the diffuser walls below the saturation temperature, causing some condensation to occur and insuring vapor flow toward the walls to eliminate the natural tendency toward separation in diffusing vapor passages.
