This study presents results of experiments where roughness applications are evaluated in delaying the tip vortex cavitation inception of an elliptical foil. High-speed video recordings and Laser Doppler Velocimetry (LDV) measurements are employed to provide further details on the cavitation behaviour and tip vortex flow properties in different roughness pattern configurations. The angular momentum measurements of the vortex core region at one chord length downstream of the tip indicate that…

Roughness Effects on the Tip Vortex Strength and Cavitation Inception

The possibility and effectiveness of roughness application to mitigate tip vortex flows are evaluated by numerical simulations of an elliptical foil. The analysis includes investigation of the


Experiments focusing on the development of a tip vortex on a rectangular NACA-66 have been performed in a towing tank. The study consists of flow visualisation by illumination with a laser sheet and

Leading Edge Roughness-A Way to Improve Propeller Tip Vortex Cavitation

Cavitation has detrimental effects on propeller performance causing high levels of radiated noise for Naval Ships and the effects on the internal environment from vibrations and noise could be very

Flow field measurement around vortex cavitation

Models for the center frequency of cavitating-vortex induced pressure-fluctuations, in a flow around propellers, require knowledge of the vortex strength and vapor cavity size. For this purpose,

Tip Vortex Cavitation Characteristics and Delay of Inception on a Three-Dimensional Hydrofoil.

Abstract : A research program was conducted to investigate both the fundamental aspects of, and techniques for delaying, tip vortex cavitation on a three-dimensional hydrofoil. The specific concepts

Attenuation of the tip vortex flow using a flexible thread

Tip vortex cavitation (TVC) is important in a number of practical engineering applications. The onset of TVC is a critical concern for navy surface ships and submarines that aim to increase their

Effect of Gas Content on Tip Vortex Cavitation

Occurrence of tip vortex cavitation (TVC) is a common problem in axial hydraulic machines. The behavior of this type of cavitation is so sensitive to variations in the flow parameters and the gas
