Acoustic force of the gravitational type

TL;DR

This paper demonstrates that, under specific conditions, Bjerknes secondary forces are attractive and proportional to the product of the virtual masses of two bubbles, contributing to the understanding of acoustic forces in fluid dynamics.

Contribution

It establishes a theoretical link between Bjerknes forces and virtual bubble masses under restrictive conditions, providing new insights into acoustic interactions.

Findings

Bjerknes forces can be attractive under certain conditions.

The force is proportional to the product of virtual masses.

The study clarifies the nature of acoustic bubble interactions.

Abstract

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 bubbles.
