Effect of low-NO X combustor swirl clocking on intermediate turbine duct vane aerodynamics with an upstream high pressure turbine stage — An experimental and computational study

Abstract:

Flow in an intermediate turbine duct (ITD) is highly complex, influenced by the upstream turbine stage flow structures, which include tip leakage flow and nonuniformities originating from the upstream high pressure turbine (HPT) vane and rotor. The complexity of the flow structures makes predicting them using numerical methods difficult, hence there exists a need for experimental validation. To evaluate the flow through an intermediate turbine duct including a turning vane, experiments were c...
