Reversible viscosity and Navier--Stokes fluids

TL;DR

This paper investigates the potential for formulating a time-reversible equation to describe fluid flows and examines its implications for understanding fluctuation statistics in stationary turbulent and laminar Navier-Stokes flows.

Contribution

It introduces a reversible formulation of fluid dynamics equations and explores their relevance to turbulence and flow fluctuations.

Findings

Reversible equations can model stationary turbulent flows.

Fluctuation statistics are affected by the reversibility of the underlying equations.

Potential links between reversibility and turbulence characteristics.

Abstract
