Second Law Analysis for the Experimental Performances of a Cold Heat Exchanger of a Stirling Refrigeration Machine [PDF]

open access: yesEntropy, 2020
The second law of thermodynamics is applied to evaluate the influence of entropy generation on the performances of a cold heat exchanger of an experimental Stirling refrigeration machine by means of three factors: the entropy generation rate N S

Thermal performance in heat exchangers by the irreversibility, effectiveness, and efficiency concepts using nanofluids [PDF]

open access: yesЖурнал інженерних наук, 2020
The objective of the work is to obtain the outlet temperatures of the fluids in a shell and tube heat exchanger. The second law of thermodynamics is applied through the concepts of efficiency, effectiveness, and irreversibility to analyze the results ...

Nonequilibrium Entropy Conservation and the Transport Equations of Mass, Momentum, and Energy

open access: yesEnergies, 2021
Nonequilibrium statistical mechanics or molecular theory has put the transport equations of mass, momentum and energy on a firm or rigorous theoretical foundation that has played a critical role in their use and applications. Here, it is shown that those

Second Law Violation By Magneto-Caloric Effect Adiabatic Phase Transition of Type I Superconductive Particles

open access: yesEntropy, 2004
: The nature of the thermodynamic behavior of Type I superconductor particles, having a cross section less than the Ginzburg-Landau temperature dependent coherence length is discussed for magnetic field induced adiabatic phase transitions from the ...

Empirical Evidence for a Law of Information Growth

open access: yesEntropy, 2001
: Based on a robust, phenomenological model for the growth of a system parameter, a relation is derived to test the evolution of such a parameter through several distinct stages.
