Annotations languages:

The results are presented for numerical study of influence HP active steam turbine blades lean and sweep on its gasdynamic characteristics. The investigations have been performed with solver FlowER, intended for numerical simulation of 3D viscous flows through multistage turbomachinery. The main lean and sweep influences on the structure of stream and local descriptions of turbine cascade are established.
Keywords: blades lean, blades sweep, abovebracer and interdisks flows
