Numerical Simulation of the Interaction between a Planar Shock Wave and a Cylindrical Bubble

Modelling
Three-dimensional (3D) computational fluid dynamics (CFD) simulations have been carried out to investigate the complex interaction of a planar shock wave (Ma = 1.22) with a cylindrical bubble. The unsteady Reynolds-averaged Navier–Stokes (URANS) approach

Spatial-temporal correlation and fluctuating propagation characteristics of bubbles based on a coupled model of oscillation and migration

Applied Ocean Research
Bubble oscillation and migration are complex dynamic processes that have been extensively studied for the applications of ocean engineering. However, the intricate coupling and interactions among various parameters that affect bubble oscillation and ...

A computationally efficient modelling of laminar separation bubbles [PDF]

The goal is to accurately predict the characteristics of the laminar separation bubble and its effects on airfoil performance. Toward this end, a computational model of the separation bubble was developed and incorporated into the Eppler and Somers ...

Bubble–bubble interaction governs nonlinear acoustic waves in polydisperse bubbly liquids

Physics of Fluids
In the weakly nonlinear regime, pressure wave propagation in bubbly liquids converts either into weak shock waves or into (acoustic) solitons by the balance of nonlinearity, dissipation, and dispersion. To predict whether such waves change to weak shock waves or solitons, it is essential to quantitatively evaluate these effects.

Measuring the effects of liquid bulk viscosity numerically on a spherical nitrogen bubble in aqueous H2SO4

AIP Advances
The current study extensively simulates multiple theories concerning the mechanism of bubble formation during the interaction between an aqueous H2SO4 solution and nitrogen gas. This interaction leads to pressure surges and high internal temperatures due
