Analysis of Blade Thickness Effects on the Cascade of Blades in Subsonic Shear Flow

概要

論文の詳細を見る
A linearized theory based on the pressure dipole method is developed for evaluating the blade thickness effects on the cascade of blades in subsonic shear flow. One of the most significant conclusions obtained from the analysis is that the blade thickness effect on the zero lift angle is strongly influenced by the spanwise gradient of the oncoming fluid velocity. The velocity gradient causes a decrease in the zero lift angle at the span stations of higher velocity and an increase at the span stations of lower velocity.
