Abstract: Numerical and experimental investigations have been performed to determine the effect of a variation of the interblade row axial gap on turbine efficiency. The geometry used in this study is the 1.5stage axial flow turbine ...

Abstract: The paper presents an experimental and computational study of the unsteady behavior of the rotor hub passage vortex in an axial lowpressure turbine. Different flow structures are identified as having an effect on the size, ...
