Periodic disturbances in swirling flows
Abstract
The origin of vortex breakdown is considered along with the occurrence of nonaxisymmetric disturbances and questions concerning the detection and the form of appearance of the disturbances. An investigation is conducted regarding the characteristics of tangential velocity, taking into account the disturbance. Attention is also given to aspects of disturbance frequency and the energy component of the disturbance.
