Vortex-bubble system as a spin acoustic particle model
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos +3
A vortices-bubble system may be depicted by some features which may lead to infer its acoustic charge and its spin angular momentum. We study the dynamics of this system within the…
Vortexes as systems specific to the Acoustic World
Ion Simaciu, Viorel Drafta, Zoltan Borsos +1
In this paper we study the properties of vortexes, as systems specific to the Acoustic World, using both hydrodynamic theory and the corresponding hydrodynamic Maxwell equations. A…
Compatibility of Maxwell's fluid equations with interactions between oscillating bubbles
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos +1
The outcome of this paper was a shape of the interaction of two oscillating bubbles. This was done to express the secondary Bjerknes force using the Maxwell equations for a liquid.…
Quantitative analysis of secondary Bjerkenes forces in various liquids
Ion Simaciu, Zoltan Borsos, Viorel Drafta +1
Numerically calculating the interaction forces between two free bubbles under the action of a background of random acoustic radiation, we highlight the contributions of radiative c…

Ion Simaciu, Zoltan Borsos, Viorel Drafta +1
Following some previous papers, we continue in this paper to give proof of the analogy between the acoustic world and the electromagnetic world. Hence we derive the expressions for…
Acoustic gravitational interaction revised
Ion Simaciu, Zoltan Borsos, Gheorghe Dumitrescu
In this paper, we deduce the expression of the gravito-acoustic force between two oscillating bubbles using the hypothesis that this type of force is a force of scattering-absorpti…
Gravitational interaction mediated by Classical Zero Point Field
Ion Simaciu, Zoltan Borsos, Viorel Drafta +1
By modeling the particle as a two-dimensional oscillator with the natural angular frequency equal to the Zitterbewegung frequency, the expression of the gravitational force between…

Ion Simaciu, Zoltan Borsos, Viorel Drafta +1
Assuming the charged particle to be a two-dimensional oscillator that scatters the classical background of zero-point field one can deduce the Coulomb force of the two interacting…
Dumb Hole Associated with an Oscillating Bubbles Cluster
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos +1
In this paper, it is shown that in interaction with an oscillating bubbles cluster the fluid becomes inhomogeneous. The radial variation of the acoustic refractive index of the flu…
Mach's Principle in the Acoustic World
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos
The aim of this paper is to investigate the coupled oscillations of multiple bubbles within a cluster. The interaction between a bubble and the other bubbles in a cluster produces…
Acoustic force of the gravitational type
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos
In this paper it was shown that, under certain restrictive conditions, Bjerknes secondary forces are attractive and proportionate to the product of the virtual masses of the two bu…
Acoustic lens associated with a radial oscillating bubble
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos
In this paper we show that a radial oscillating bubble in a liquid behaves like a convergent acoustic lens.
Deviation of the waves in an inhomogeneous medium
Ion Simaciu, Zoltan Borsos, Gheorghe Dumitrescu
Using the formula found by Noorbala and Sepehrinia, the wave deviation in an inhomogeneous medium with continuous variation of propagation velocity is deduced. For electromagnetic…
Acoustic scattering-extinction cross section and the acoustic force of electrostatic type
Ion Simaciu, Zoltan Borsos, Gheorghe Dumitrescu +2
The analysis of the secondary Bjerknes force between two bubbles suggests that this force is analogous to the electrostatic forces. The same analogy is suggested by the existence o…
Interactions in an acoustic world
Ion Simaciu, Gheorghe Dumitrescu, Zoltan Borsos +1
The present paper aims to complete an earlier paper where the acoustic world was introduced. This is accomplished by analyzing the interactions which occur between the inhomogeneit…

We propose a kinetic equation for a special kind of acceleration: chaotic gun effect. Then we infer a distribution function which can depict the instability condition. With this di…
