An investigation into the pressure distribution in a turbine nozzle cascade with and without leaned blades has been made using a 3D subsonic variational FEM. We can conclude from our studies that the gas flow circulation is the essential factor of redistributing the secondary flow loss along the blade height in a leaned cascade. In addition, this paper recommends a direction for further research into the leaned stator cascade.
