On the mechanism of generation of the Kelvin-Helmholtz instability

TL;DR

This paper explores the Kelvin-Helmholtz instability mechanism, showing how it generates velocity shear and redistributes flow energy, based on the Kutta-Zhoukovsky theorem.

Contribution

It introduces a novel explanation of the instability mechanism rooted in classical fluid dynamics principles.

Findings

Identifies the flow energy redistribution process

Links the instability to the Kutta-Zhoukovsky theorem

Provides insight into the generation of velocity shear

Abstract

Mechanism of the Kelvin-Helmholtz instability based on the Kutta-Zhoukovsky theorem is considered. The mechanism itself generates the velocity shear, thereby redistributing the flow energy which drives the instability.
