Aerodynamic influence of rim seal purge flow injection on the main flow in a 1.5-stage axial turbine with non-axisymmetric end wall contouring

This paper presents an investigation of the aerodynamic influence of rim seal purge flow injection on the main flow in a 1.5-stage turbine with non-axisymmetric end walls and a bowed stator using experimental flow measurements and unsteady RANS simulations. The study focuses on the secondary vortex...
