Adjoint-based optimisation of rocket engine turbine blades

Axial turbine stages for gas generator cycle type rocket engines typically employ highly-loaded supersonic stator vanes. Consequently, the flow pattern downstream of the vanes is characterized by shock waves which induce high-frequency excitation on the subsequent rotor. For this reason, the optimal design of the stator is crucial in the context...

Effect on a shock wave boundary layer interaction of air jet vortex generators

The effect of upstream injection by means of continuous Air Jet Vortex Generators (AJVGs) on a shock wave turbulent boundary layer interaction is experimentally investigated. The baseline interaction is of the impinging type, with a flow deflection angle of 9.5?, a Mach number Me = 2.3, and a momentum thickness based Reynolds number of 5,000....
