2418 Numerical and Experimental Investigations on Three-Dimensional Unsteady Aerodynamic Interaction in a Turbine Stage
Details
Three-dimensional unsteady aerodynamic interaction in a turbine stage, which has a great effect on aerodynamic stage performance, has attracted attention from researchers. To elucidate this effect, we have investigated the flow field by using high-precision three-dimensional Navier-Stokes solver ; where blade-count ratio is almost the same as that of a real turbine. Axial spacing between rotor and stator is changed. We have compared experimental timeaveraged pneumatic pressure data measured by five-hole pitot probe with numerical results.
