Abstract

Many of the problems resulting from the formation and behaviour of the liquid phase in steam turbine blading can be more easily investigated in two-dimensional cascades. To reproduce turbine nucleating and wet steam conditions realistically requires a supply of supercooled steam. The paper is a review article, giving the features of a blow-down cascade tunnel constructed for the purpose and summarizes the results reported. Results obtained in steady supersonic tunnels are also discussed.
