• 論文の詳細を見る

• A method of singularity is developed for the analysis of aerodynamic responses of turbine rotor blade to sinusoidal gust of large vorticity. It is shown that the upstream gust suffers a significant distortion within the passage of finite-loaded cascade because of the conservation law of vorticity, which has been taken into account in the analysis. The numerical results reveal some notable influences of finite steady loading and higher order harmonics in the gust on the unsteady pressure, fluid forces and wake vortex energy of turbine rotor blade.
