The tip-leakage vortex (TLV) cavitation is a challenging issue for a variety of axial hydraulic
turbines and pumps from both technical and scientific viewpoints. The flow characteristics of …

In the present paper, a new control method for tip-leakage vortex (TLV) cavitation is
proposed. This method, which combines the effects of grooves and winglets, is made of …

The tendency of designing large Kaplan turbines with a continuous increase of output power
is bringing to the front the cavitation erosion issue. Due to the flow in the gap between the …

Tip leakage vortex (TLV) usually exists at a small tip clearance in axial-flow energy
conversion machines, which may induce flow loss, vibration, noise and vortex cavitation. In …
