FINITE SYMMETRIC DISTURBANCES PROPAGATION IN A VORTEX CORD

Central Aerohydrodynamic Institute (TsAGI) 1, Zhukovsky str., Zhukovsky, 140180, Moscow region, Russia

ABSTRACT

The process of disturbances propagation along a vortex cord is considered under the assumption of inviscid fluid. It is shown that the cord tends to have a stepped form. The velocity of propagation for this form is calculated.
