Influence of Rotor Dimple Geometry on Cavitation Characteristics of Rotational Cavitation Generator

open access: yesIOP Conference Series: Earth and Environmental Science, 2022
Abstract The current investigation is aimed to simulate the internal flows in a rotational cavitation generator with a rotor and a stator by using the RNG k-ε turbulence model and Zwart-Gerber-Belamri cavitation model. The design of the cavitation generator is that the rotor is provided with surface dimples.

The Cavitation Characteristics of MAU Type Propeller

open access: yesJournal of the Society of Naval Architects of Japan, 1977
In this paper the authors study the improvement method of cavitation characteristics of MAU type propeller.The “two-dimensional cavitation bucket chart” which was developed by Gutsche, Nakajima, Ito, etc., is insufficient to predict cavitation of a propeller because it is originally based on two-dimensional sections.

Fluid Dynamic Characteristics and Flow Distribution ‎Structure Optimization of Axial Piston Pump Considering ‎Cavitation Bubble Evolution

open access: yesJournal of Applied Fluid Mechanics, 2021
An axial piston pump can produce a serious cavitation phenomenon in the high- and low-pressure ‎transition process. Cavitation bubbles expand, compress, rebound and collapse when they enter the high-‎pressure oil drainage area.
