Shock wave configuration in a transonic flow through a mid-section of a last stage turbine blade cascade equipped with a part-span connector

This paper deals with the study of a flow field and namely configuration shock waves in blade cascade equipped part-span connector called tie-boss. The consists prismatic blades formed from mid-section very long last-stage steam turbine. is based on numerical simulations through that was previously tested wind tunnel. Commercial software Ansys CFX used for ICEM mesh generation. computational domain contains non-homogenous interfaces. showed presence tie-boss has profound effect waves. exit are disturbed new lateral introduced into flow.
