Y. Dubief, V. E. Terrapon, J. Soria
TL;DR
This paper discusses the discovery and characteristics of Elasto-Inertial Turbulence, a new chaotic flow state in dilute polymer solutions where inertial and elastic effects interplay, influenced by Reynolds number.
Contribution
It introduces Elasto-Inertial Turbulence as a novel flow state, supported by recent numerical and experimental evidence, expanding understanding of turbulence in polymer solutions.
Findings
Elasto-inertial turbulence is a chaotic flow state in polymer solutions.
Both inertial and elastic effects influence the flow dynamics.
The relative contributions of these effects vary with Reynolds number.
Abstract
This movie illustrates the recent numerical and experimental discovery of a new state of turbulence in dilute polymer solutions, Elasto-Inertial Turbulence. Elasto-inertial turbulence is characterized by a chaotic flow state in which both inertial and elastic effects, whose relative contributions vary with the Reynolds number, control the flow dynamics.
