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.

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.
