A review of methods for vortex identification in hydroturbines
TL;DR: A review of vortex identification methods for hydroturbines can be found in this paper, where the authors classified five different taxonomies based on five types of vortices (e.g. vortex rope in draft tube, Karman vortex, and inter-blade vortex) and discussed experimental techniques for vortex observation.

Experimental study on bubble dynamics subject to buoyancy
TL;DR: In this paper, the dynamics of large bubbles subject to various strengths of buoyancy effects, which are associated with applications for underwater explosion, are investigated. But the results are limited to the case where the bubbles recorded are transparent, and thus they are able to display and study the jet formation, development and impact on the opposite bubble surface.

Study on splitting of a toroidal bubble near a rigid boundary
A-Man Zhang,Shuai Li,J. Cui +2 more
TL;DR: In this article, the boundary integral method was used to simulate the interaction between two toroidal bubbles after splitting, and the authors investigated buoyancy and non-buoyancy cases.

Small-charge underwater explosion bubble experiments under various boundary conditions
P. Cui,A-Man Zhang,S.P. Wang +2 more
TL;DR: In this paper, a detailed image analysis on the final stages of bubble collapse was carried out and revealed a possible explanation for the weakening of pressure waves at bubble rebound as the bubble approaches a wall boundary.

A level set approach for computing solutions to incompressible two-phase flow
TL;DR: A level set method for capturing the interface between two fluids is combined with a variable density projection method to allow for computation of two-phase flow where the interface can merge/break and the flow can have a high Reynolds number.

An Efficient, Interface-Preserving Level Set Redistancing Algorithm and Its Application to Interfacial Incompressible Fluid Flow
Mark Sussman,Emad Fatemi +1 more
TL;DR: This paper implements a "constraint" along with higher order difference schemes in order to make the iteration method more accurate and efficient, and shows that the "distance level set scheme" with the added constraint competes well with available interface tracking schemes for basic advection of an interface.

Growth and collapse of a vapour cavity near a free surface
John Blake,D. C. Gibson +1 more
TL;DR: In this paper, an approximate integral-equation approach is used to model the growth and collapse of a vapour cavity in close proximity to an initially plane free surface, and features observed and predicted include the formation of an accelerating liquid jet in the bubble and a pronounced spike in the free surface during the collapse phase of the bubble's life.
