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: This paper addresses the unsteady formation of secondary flow structures inside a turbine rotor passage. The first stage of a twostage, lowpressure turbine is investigated at a Reynolds Number of 75,000. The design represents ...
