Stability of Infinitely Long Asymmetrical Vortex Rope
Original language description
Eigen value analysis of cavitating vortex rope motion was carried out. Analysis is based on Euler equation, continuity equation and Laplace equation of stress in shell. Instability, which depends on angular velocity of the fluid rotation and radii of vortex rope and draft tube, is judged according to sign of the real part of eigen value. Resulting eigen mode shapes indicate existence of vortex rope shape with elliptical cross-section as was previously documented experimentally.

Stabilita nekonečně dlouhého vírového copu
Czech description
V článku je uveden výpočet vlastních hodnot nekonečně dlouhého vírového copu. Jedná se o výpočet Eulerovy rovnice, rovnice kontinuity a Laplacevy rovnice pro napětí na povrchu copu. Nestabilita závisí na úhlové rychlosti kapaliny a poloměru vírového copu.
