概要

• 論文の詳細を見る

• The steady and unsteady three-dimensional velocity distributions between the stator blades due to passing wakes shed by upstream moving cylinders are measured. The method utilizes hot-wire located in three-coordinate directions respectively. By using "average response technique" on all hot-wire signal, the fluctuating component due to the Karman vortex is suppressed, and only the periodic component is extracted. The motion of the wake passing through the stator blade row and the effect of it on flow in a passage are considered and compared with the measured results of the unsteady force on the blade.
