Fluid-Structure Interaction Mechanisms for Close-In Explosions

Shock and Vibration, 2000
This paper examines fluid-structure interaction for close-in internal and external underwater explosions. The resulting flow field is impacted by the interaction between the reflected explosion shock and the explosion bubble.

Recent observations on cavitation and cavitation noise [PDF]

, 1989
This paper is primarily concerned with the acoustics of traveling bubble cavitation around foils or headforms. We begin with observations of individual bubbles and the acoustic signals they emit, our purpose being to identify areas of research which ...

Magnetar Driven Bubbles and the Origin of Collimated Outflows in Gamma-ray Bursts

, 2007
We model the interaction between the wind from a newly formed rapidly rotating magnetar and the surrounding supernova shock and host star. The dynamics is modeled using the two-dimensional, axisymmetric thin-shell equations.

Positronium in a liquid phase: formation, bubble state and chemical reactions

, 2012
This chapter reviews the following items: 1. Energy deposition and track structure of fast positrons: ionization slowing down, number of ion-electron pairs, typical sizes, thermalization, electrostatic interaction between e+ and its blob, effect of local

Theoretical study on the movements of bubbles

Ultrasonics Sonochemistry
The radial and translational motions of multiple interacting spherical bubbles are obtained using classical Newton mechanics. It is seen that bubbles not only move in straight line, but also in circular motion.

Analysis of bubble distribution in a multiphase rotodynamic pump

Engineering Applications of Computational Fluid Mechanics, 2019
Recent researches show that the pressure increment of a multiphase pump is affected by bubble size and distribution. In order to study the bubble distribution characteristics in such pumps, a novel approach describing the variable bubble size in the pump
