EXPERIMENTAL INVESTIGATION OF BLADE GRIDS AND TURBINE STAGES DESIGNED BY CFD
Tajč L., Šiková I.
pages 287 - +8p., full text

Experimental investigation of profile and secondary losses is presented here. The loss coefficients of different types of blade cascades are evaluated, the efficiency of turbine stages is measured. The quality of profiles designed for the subsonic and transonic flow, as well as the tip and hub and walls design of turbine stages were tested on an aerodynamic wind tunnel and on an experimental steam turbine. 3D design of blades is described in the paper.
