概要

• 論文の詳細を見る

• The effects of the fluid viscosity on the unsteady forces on cascade blades are investigated based on a linearized Navier-Stokes equation on the assumption that the perturbations are small. Also the sinusoidal dissipating gusts are introduced on the same assumption and the lift and drag response of the cascades to the flow and the forces on the up and downwards vibrating blades are calculated. It is found that the viscosity of the fluid works so as to enlarge the amplitude of the unsteady forces but it has not so much effects on the phase of the lifts.
