Which consequence results when blade tip speed increases severely in shrouded turbines?

💡 Explanation

The rotating blades generate considerable turbulence; therefore, there is increased flow-induced vibration during high turbulence due to vortex shedding behind stalled blades rather than efficient steady-state operation, because viscous losses dominate flow oscillations at small scales.
