内容記述 | In present study, the unsteady effect of rotor-stator interaction on turbine stage performance was investigated. Unsteady RANS simulations were performed to clarify the unsteady three-dimensional flow field in a turbine stage. Concerning the flow field at midspan in the rotor, so-called 'negative jet' due to the wake was confirmed, which is similar to 2D calculation results. Simulation results also showed that inward radial flow was followed by the wake. The strong secondary flow was periodically generated by the wake passing through the rotor, and then the passage vortex near the endwall fluctuated in the radial direction. It was found that the total pressure loss coefficient in the unsteady calculation was almost 12 percent higher than that in the steady calculation. | |||||
