Thermo-Mechanical and Mdchano-Thermal Effects in Liquids Explained by means of the Dual Model of Liquids

TL;DR

This paper demonstrates that the Dual Model of Liquids can effectively explain complex thermo-mechanical effects in liquids, including thermodiffusion and a newly observed mechano-thermal effect, providing theoretical insights into these phenomena.

Contribution

It introduces the Dual Model of Liquids as a comprehensive framework to explain thermodiffusion and mechano-thermal effects in non-equilibrium liquids, including novel effects.

Findings

Correctly models positive and negative Soret coefficients

Provides the first theoretical interpretation of a recent mechano-thermal effect

Demonstrates the Dual Model's capability in non-equilibrium thermodynamics

Abstract

We pursue to illustrate the capabilities of the Dual Model of Liquids showing that it may explain crossed effects notable in Non-Equilibrium Thermodynamics. The aim of the paper is to demonstrate that the DML may correctly model the thermodiffusion, in particular getting formal expressions for positive and negative Soret coefficient, and another unexpected mechano-thermal effect recently discovered in liquids submitted to shear strain, for which the first-ever theoretical interpretation is provided.
