概要

• 論文の詳細を見る

• Two parallel rotating disks induce an unsteady flow which may be represented by a non -axisymmetric perturbation superimposed upon a rigid rotation of the fluid as a whole. The flow instability occurs as a wave propagating in the azimuthal direction. A secondary flow is observed by the smoke-wire technique of flow visualization. In order to ascertain the mechanism of the instability, a swirling flow with a region of finite thickness in which the velocity decreases from a maximum value to zero is considered. The velocity distribution of the secondary flow, as obtained by inviscid linearized stability theory, shows good agreement with the observed flow pattern.
