Abstract

As part of an investigation to study the removal of water from the trailing edge of a low pressure steam turbine fixed blade by suction slots, experiments were made on a perspex test section in which a 1-in wide section of the suction slot was simulated. The flow characteristics are considered of the passage in the choked condition and a comparison is made with some two-phase critical flow theories. The theories are briefly presented and discussed, and the relevant formulae given. It is found that the homogeneous-equilibrium model grossly underestimates the discharge rates whilst all of the other flow models overestimate by at least 30 per cent.
