Swirling flows are very susceptible to instabilities. Very often they are present in draft tubes of hydraulic turbines as so called vortex ropes resulting from spiral vortex breakdown. Moreover the situation can be complicated by cavitation within the core of the vortex. Paper presents various approaches, which were applied to enhance understanding of this problem. Numerical approach to study the linear stability including influence of cavitation is proposed and extensive nonlinear CFD simulations are described.
