Abstract
By maintaining a circumferentially-continuous, rotating film of water on the housing of a water-cooled gas turbine, kinetic energy imparted to the cooling water droplets by rotational velocity of the turbine bucket shrouds is partially absorbed in the film when struck by the droplets, thereby reducing erosive effects on the turbine housing resulting from droplets slamming the housing.
