abstract

A new profile has recently been developed at Kraftwerk-Union (KWU), West Germany, to increase the efficiency of todays high pressure (HP) and intermediate pressure (IP) steam turbines. The profile was described using analytical functions. Therefore, the contour could be easily modified until the surface pressure distributions, which were calculated using a singularity method, fit a desired distribution. The experiments for the aerodynamic cascade data and blade surface pressure distributions were performed at the German Aerospace Research Establishment (DFVLR), Institute for Experimental Fluid Dynamics in Goettingen. Computer codes developed at the Institute enabled additional theoretical studies. The codes used in the study included a time-marching method for calculating the 2D-flow field and an integral method for calculating the boundary layer. Both theoretical and experimental results are discussed and compared with efficiency measurements derived from a multistage testrig at KWU.
