Vortex-bubble system as a spin acoustic particle model

TL;DR

This paper models a vortex-bubble system in fluid physics as an acoustic particle with charge and spin, using Maxwell's hydrodynamic equations, revealing stability properties and potential for representing particles in the Acoustic World.

Contribution

It introduces a novel vortex-bubble system model that captures acoustic charge and spin, linking fluid dynamics with particle-like properties in the Acoustic World.

Findings

The bubble in the vortex core is more stable than outside.

The system can represent an acoustic particle with charge and spin.

Neglecting viscosity, gravity, and radiation simplifies the model.

Abstract

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 framework of fluid physics and with the help of Maxwell's hydrodynamic equations. Since we will adopt an approach of a fluid without viscosity and without gravity, then the fluid is in steady state if also we will neglect the acoustic radiation. When we expressed the energy (the kinetic and potential energy) of the vortex-bubble system we found out that the state of bubble which is captured in the core of the vortex is more stable than it is out of the core. For the above allegations we consider that this system, namely a vortex-bubble system, is a good approach for an acoustic particle with charge and spin angular momentum. This system owns to the Acoustic World.
