Dynamic behavior of the cavitation bubbles collapsing between a rigid wall and an elastic wall
AIP Advances, 2021 There are various bubble cavitation phenomena in daily production and life, and near-wall cavitation is the most common one. This paper studies the bubble cavitation dynamics between a rigid wall and an elastic wall, and by changing the distance between ...

Numerical Evaluation of Cavitation Erosion Intensity around NACA0015 Hydrofoil Based on Eulerian-Lagrangian Approach [PDF]
مهندسی مکانیک شریف, 2022 In this study, to investigate the intensity of cavitation-induced erosion, the bubble behavior around the NACA0015 2D hydrofoil was simulated from the Eulerian-Lagrangian perspective.

A bubble fission model for collapsing cavitation bubbles
Physics of Fluids, 2004 A bubble fission model that takes into account energy dissipation during violent collapses of cavitation bubbles is introduced by assuming volume conservation and continuity of the gas pressure during instantaneous breakup, invoking either Rayleigh–Taylor instability or high speed microjet formation.

Numerical Study of the Pulsation Process of Spark Bubbles under Three Boundary Conditions
Journal of Marine Science and Engineering, 2021 In this study, a compressible three-phase homogeneous model was established using ABAQUS/Explicit. These models can numerically simulate the pulsation process of cavitation bubbles in the free field, near the flat plate target, and near the curved ...

A numerical model for cloud cavitation based on bubble cluster
Theoretical and Applied Mechanics Letters, 2017 The cavitation cloud of different internal structures results in different collapse pressures owing to the interaction among bubbles. The internal structure of cloud cavitation is required to accurately predict collapse pressure.

Fission of collapsing cavitation bubbles [PDF]
Journal of Fluid Mechanics, 2002 High-speed observations clearly show that though a collapsing cavitation bubble approaches its minimum size as a coherent single volume, it usually reappears in the first rebounding frame as a cloud of much smaller bubbles or as a highly distorted single volume.

Journal of Fluid Science and Technology, 2010 We developed a numerical simulation code and a method of estimation for predicting the cavitation erosion in pumps. Cavitation erosion is closely related to cavitation intensity based on bubble dynamics.

Research on the Cavitation Flow Characteristics and Transport Mechanism of Rotating Cascades [PDF]
Journal of Applied Fluid MechanicsIn this study, a numerical simulation combining the Detached Eddy Simulation (DES) model with the Zwart Gerber Belamari (Z-G-B) cavitation model is used, along with a visualization experiment, to analyze cavitation flow within a rotating cascade.
