Simulation of 3D Flows of Propulsion Systems Using an Efficient Low Diffusion E-CUSP Upwind Scheme

A newly suggested E-CUSP upwind scheme is employed for the first time to calculate 3D flows of propulsion systems. The computed cases include a transonic nozzle with circular-to-rectangular cross section, a transonic duct with shock wave/turbulent boundary layer interaction, and a subsonic 3D compressor cascade. The computed results agree well with the experiments. The new scheme is proved to be accurate, efficient and robust for the 3D calculations of the flows in this paper.
