Experimental investigation of three- dimensional flow characteristics in turbine blade cascade

Eksperimental investigation of the flow characteristics in three-dimensional boundary layers in the large scale turbine blade cascade was carried out. The visualization of current was fulfilled for preliminary analysis of the flow structure on the endwall of blade channel. Then the distribution of velocity components and flow angles in three-dimensional boundary layers was measured in detail. On basis of the investigation results the generalized equations for calculation of boundary layer characteristics were created.
