#### Resonance properties of soluble gas bubbles

(2006)

Soluble gas bubbles in a liquid experiencing radial oscillations created by an acoustic field are considered. It is shown that the resonance frequency of large soluble gas bubbles practically coincides with the natural ...

#### Duhamel integral form for the interface heat flux between bubble and liquid

(2007)

The solution of heat equation inside oscillating gas bubble with moving boundary was obtained by Fourier's method. The integral formula for interface heat flux, containing theta-function in the integrand was derived. The ...

#### Diffusion effects in the oscillation of vapor-gas bubbles in a sound field

(2007)

The gas-vapor bubbles oscillating in the acoustic field are considered. The diffusion of gas and vapor components inside the bubble is taken into account. The analytical formula is obtained for the amplitude of the ...

#### Numerical analysis of micellar-polymer displacement of oil from flooded strata

(2006)

Mathematical modeling of the process of flooding of an oil-bearing bed by a micellar-polymer mixture is developed. A model of the process is developed in the framework of isothermal flow of a multiphase, multicomponent ...

#### Nonlinear interaction and reflection of waves in vapor-liquid bubbly mixtures

(2007)

A mathematical model was developed for investigation of waves in bubbly liquids with planar, cylindrical and spherical symmetry. The problems of reflection of waves from free surface and rigid wall and interaction of waves ...

#### Dynamics of radial oscillations and translatory motion of the bubbles in solution

(2009)

The model describing the behavior of vapor bubbles in solution is presented. The model takes into account the translatory motion of the bubble accompanied by radial oscillations and heat-mass transfer effects. It is shown ...

#### The structure of roots of the characteristic equation for free oscillations of a gas bubble in liquid

(2009)

A study was conducted to demonstrate the structure of roots of the characteristic equation for free oscillations of a gas bubble in liquid. The structure of the roots of the dispersion equation was investigated in detail ...

#### Toward the problem of the resonances of a bubble radially pulsating in a liquid

(2009)

Gas bubbles performing radial pulsations under the action of an acoustic field are analyzed. It is shown in detail that gas bubbles of constant mass may have only one resonance frequency. � 2009 Springer Science+Business ...
