An action principle of classical irreversible thermodynamics -\n Irreversible thermodynamic cycles and embodied bits of information [PDF]
, 2016 Despite its simplicity, it seems to my best of knowledge that the possibly simplest approach towards deriving equations governing irreversible thermodynamics from gas-kinetic considerations within the framework of classical mechanics has never been pursued.

On the Role of External and Internal Irreversibilities towards Classical Entropy Generation Predictions in Equilibrium Thermodynamics and their Relationship with Heat Transfer [PDF]
The Open Thermodynamics Journal, 2008 In classical equilibrium thermodynamics description, ambiguities exist in terms of pinpointing external and in- ternal irreversibilities in overall entropy generation prediction, as a system undergoes a thermodynamic process. The pre- sent work attempts to bridge this gap between classical thermodynamics-based irreversibility predictions and finite ...

A Variational Formulation for Irreversible Thermodynamics with Path Dependence. [PDF]
Entropy (Basel)This work introduces a path-dependent energy Lagrangian for irreversible thermomechanics that embeds heat and entropy accounting directly into the action. The formulation requires neither Lagrange multipliers nor Rayleigh potentials.

Incremental least action principle in the framework of thermodynamics of irreversible processes
Physical Review Research, 2020 In this paper, an incremental least action principle is proposed using the framework of the thermodynamics of irreversible processes. First, we establish that an extensive thermodynamic potential defined over an infinitesimal volume satisfies a ...

A Pedagogical Reinforcement of the Ideal (Hard Sphere) Gas Using a Lattice Model: From Quantized Volume to Mechanical Equilibrium [PDF]
EntropyDue to their simplicity and ease of visualization, lattice models can be useful to illustrate basic concepts in thermodynamics. The recipe to obtain classical thermodynamic expressions from lattice models is usually based on invoking the thermodynamic ...

Entropy Production in an Electro-Membrane Process at Underlimiting Currents—Influence of Temperature [PDF]
EntropyThe entropy production in the polarization phenomena occurring in the underlimiting regime, when an electric current circulates through a single cation-exchange membrane system, has been investigated in the 3–40 °C temperature range. From the analysis of

Extended irreversible thermodynamics of heat transport. A brief introduction; pp. 118–126 [PDF]
Proceedings of the Estonian Academy of Sciences, 2008 Current frontiers of technology require generalized transport equations incorporating memory, non-local effects, and non-linear effects. Extended Irreversible Thermodynamics provides such transport equations in a form compatible with the second law of ...

Computational analysis of heat transfer augmentation and thermodynamic irreversibility of hybrid nanofluids in a tube fitted with classical and elliptical‑cut twisted tape inserts [PDF]
Journal of Thermal Analysis and Calorimetry, 2022 AbstractThis work investigates heat transfer and entropy generation of a turbulent flow of an Al2O3–Cu/water hybrid nanofluid in a plain tube (PT) with classical (TPT) and elliptical‑cut twisted tape (TECT) inserts. The heat transfer and pressure drop are investigated numerically at Re (7000–15,000), mass concentration (1–4%), and the inlet temperature
