Nonlinear oscillations following the Rayleigh collapse of a gas bubble in a linear viscoelastic (tissue-like) medium

In a variety of biomedical engineering applications, cavitation occurs in soft tissue, a viscoelastic medium. The present objective is to understand the basic physics of bubble dynamics in soft tissue. To gain insights into this problem, theoretical and numerical models are developed to study the Rayleigh collapse and subsequent oscillations of a gas bubble in a viscoelastic material. To accoun...

Oscillations of a layer of viscoelastic fluid under steady forcing

We study the dynamics of a layer of viscoelastic fluid, in the Stokesian regime, that is driven from below by a 4 4 checkerboard pattern of rotating and counter-rotating disks. At low disk rotation rate (low Weissenberg number) the fluid flow response is slaved to the geometry of this forcing and divides into many steadily rotating cells, each contained within invariant manifolds issuing from h...

Numerical Study of a Gas Bubble Rising Through Stagnant Fluid

It is well known that the environment degradation has come along the time positioning as one of the main problems from modern world. Among several questions of the environmental interest the methane bubble rise in the lakes can be emphasized, from the anoxic sediment in the bottom of lake until water interface atmosphere. In particular, the present academic work has come to treat mathematic mod...

Simulation of a cusped bubble rising in a viscoelastic fluid with a new numerical method

We developed a new lattice Boltzmann method that allows the simulation of two-phase flow of viscoelastic liquid mixtures. We used this new method to simulate a bubble rising in a viscoelastic fluid and were able to reproduce the experimentally observed cusp at the trailing end of the bubble.  2000 Elsevier Science B.V.

Influences of magnetic field in viscoelastic fluid

This communication influences on magnetohydrodynamic flow of viscoelastic fluid with magnetic field induced by oscillating plate. General solutions have been found out for velocity and shear stress profiles using mathematical transformations (Integral transforms). The governing partial differential equations have been solved analytically under boundary conditions u(0,t)=A_0 H(t)sinΩt and u(0,t)...
