# Formation of structure for gas-liquid, non-equilibrium polymer media

## TL;DR

This paper explores how external acoustic fields influence bubble dynamics in gas-liquid polymer media, leading to mechanical changes in macromolecules such as destruction and synthesis during bubble collapse.

## Contribution

It introduces a mechanism linking bubble collapse under acoustic excitation to macromolecular synthesis and destruction in non-equilibrium polymer systems.

## Key findings

- Bubble collapse induces polymer chain destruction and synthesis.
- Flow geometry and sound oscillations significantly affect bubble dynamics.
- Mechanically-induced kinetic changes are driven by bubble behavior.

## Abstract

This paper examines the mechanisms of destruction and synthesis for macromolecules, which may be propelled by external acoustic fields in the flows of polymeric liquids containing a large number of gas bubbles. The dynamics of these bubbles is assumed to govern by changing the flow geometry and exciting sound oscillations in the flow. Mechanically-induced kinetic changes in macromolecules (destruction and synthesis of polymer chains) will occur when the bubbles collapse.
