Investigation of cavitation bubble dynamics near an asymmetric hydrofoil
Abstrak
The dynamic behavior of a cavitation bubble near an asymmetric hydrofoil is investigated experimentally through high-speed photography and theoretically using a Kelvin impulse model. The typical deformations arising during bubble collapse near the hydrofoil are analyzed qualitatively. The effects of the bubble position and the hydrofoil’s eccentricity angle are analyzed quantitatively. The spatial distribution of the Kelvin impulse near the hydrofoil are explored. Different morphological evolutions of a bubble near an asymmetric hydrofoil are revealed, with B-shaped, heart-shaped, and arc-shaped collapses. The velocity of the bubble interface close to the hydrofoil is significantly affected by the bubble–hydrofoil distance and the hydrofoil’s eccentricity angle, increasing as both the distance and the eccentricity angle grow. It is found that the Kelvin impulse sensitivity varies at different positions with respect to the asymmetric hydrofoil, being higher at the head and tail, and lower in the middle.
