Special Issue Information

Dear Colleagues,

The Second Law of Thermodynamics is a fundamental law of the universe, and its ubiquity can be proven by demonstrating its equivalence across all types of thermodynamic systems. This law dictates the direction of energy transfer, which is always from a higher to a lower potential and is always irreversible. It sets the conditions for transferring mass and energy and, thus, the limitations of such processes. This simplicity of causation drives the inexorable movement of energy toward an equilibrium.

The need to delve further into the Second Law of Thermodynamics is essential. This Special Issue intends to assess certain physical and philosophical concepts, to spark dialogue and thoughtful criticism, including certain recent debates, as well as to gain a deeper understanding of the fundamental principles of the Second Law of Thermodynamics.

The Second Law of Thermodynamics is a significant and unassailable rule in physics, engineering, and, more generally, the natural world. It has been known for over 150 years and is usually considered the most authoritative law.

Earlier, Einstein firmly stated that “Thermodynamics is the only universal physical theory that will never be refuted”. The Second Law and other thermodynamics principles are connected to many perplexing matters that require delicate descriptions and fuzzy interpretations. 

We invite contributions to discuss the fundamental aspects of the Second Law of Thermodynamics, including entropy as a significant physical quantity characterizing a thermodynamic system and entropy generation as an indicator of irreversibility in a thermodynamic process.

We welcome all sorts of relevant topics, such as (but not limited to):

  • Entropy and the Second Law;
  • Clausius equality and inequality;
  • The reversibility and irreversibility of thermodynamic processes;
  • Statistical thermodynamics;
  • The Second Law of Thermodynamics within a classical and quantum description;
  • Low-temperature studies and experiments within the Second Law of Thermodynamics;
  • Bose–Einstein condensation and the Second Law of Thermodynamics;
  • Quantum coherence, entanglement, and the Second Law;
  • Maxwell’s demon and further challenges;
  • The Second Law in Cosmology, Gravitation, and Astrophysics.

It is our desire that this Special Issue motivates researchers and specialists to take a closer look at the Second Law of Thermodynamics—one of the most influential fundamental laws of nature—and the issues relevant to it.

This work recalls the basic thermodynamics of chemical processes for introducing the evaluation of the nuclear reactions’ spontaneity. The application and definition of the thermodynamic state functions of the nuclear processes have been described by focusing on their contribution to the chemical potential. The variation of the nuclear binding potentials involved in a nuclear reaction affects the chemical potential through a modification of the internal energy and of the other state functions. These energy changes are related to the mass defect between reactants and products of the nuclear reaction and are of the order of magnitude of 1 MeV per particle, about six orders of magnitude larger than those of the chemical reactions. In particular, this work assesses the Gibbs free energy change of the fusion reactions by assuming the Qvalue as the nuclear contribution to the chemical potential and by calculating the entropy through the Sackur–Tetrode expression. Then, the role of the entropy in fusion processes was re-examined by demonstrating the previous spontaneity analyses, which assume a perfect gas of DT atoms in the initial state of the fusion reactions, are conservative and lead to assessing more negative ΔG than in the real case (ionized gas). As a final point, this paper examines the thermodynamic spontaneity of exothermic processes with a negative change of entropy and discusses the different thermodynamic spontaneity exhibited by the DT fusion processes when conducted in a controlled or uncontrolled way.

Bridgman once reflected on thermodynamics that the laws of thermodynamics were formulated in their present form by the great founders of thermodynamics, Kelvin and Clausius, before all the essential physical facts were in, and there has been no adequate reexamination of the fundamentals since. Thermodynamics still has unknown possibilities waiting to be explored. This paper begins with a brief review of Clausius’s work on the second law of thermodynamics and a reassessment of the content of Clausius’s statement. The review tells that what Clausius originally referred to as the second law of thermodynamics was, in fact, the theorem of equivalence of transformations (TET) in a reversible cycle. On this basis, a new symmetric form of Clausius’s TET is proposed. This theorem says that the two transformations, i.e., the transformation of heat to work and the transformation of work from high pressure to low pressure, should be equivalent in a reversible work-to-heat cycle. New thermodynamic cyclic laws are developed on the basis of the cycle with two work reservoirs (two pressures), which enriches the fundamental of the second law of thermodynamics. Full article

Modern concepts in irreversible thermodynamics are applied to system transformation and degradation analyses. Phenomenological entropy generation (PEG) theorem is combined with the Degradation-Entropy Generation (DEG) theorem for instantaneous multi-disciplinary, multi-scale, multi-component system characterization. A transformation-PEG theorem and space materialize with system and process defining elements and dimensions. The near-100% accurate, consistent results and features in recent publications demonstrating and applying the new TPEG methods to frictional wear, grease aging, electrochemical power system cycling—including lithium-ion battery thermal runaway—metal fatigue loading and pump flow are collated herein, demonstrating the practicality of the new and universal PEG theorem and the predictive power of models that combine and utilize both theorems. The methodology is useful for design, analysis, prognostics, diagnostics, maintenance and optimization. Full article

We study Einstein’s gravity coupled to nonlinear electrodynamics with two parameters in anti-de Sitter spacetime. Magnetically charged black holes in an extended phase space are investigated. We obtain the mass and metric functions and the asymptotic and corrections to the Reissner–Nordström metric function when the cosmological constant vanishes. The first law of black hole thermodynamics in an extended phase space is formulated and the magnetic potential and the thermodynamic conjugate to the coupling are obtained. We prove the generalized Smarr relation. The heat capacity and the Gibbs free energy are computed and the phase transitions are studied. It is shown that the electric fields of charged objects at the origin and the electrostatic self-energy are finite within the nonlinear electrodynamics proposed. Full article

Entropy generation, formulated by combining the first and second laws of thermodynamics with an appropriate thermodynamic potential, emerges as the difference between a phenomenological entropy function and a reversible entropy function. The phenomenological entropy function is evaluated over an irreversible path through thermodynamic state space via real-time measurements of thermodynamic states. The reversible entropy function is calculated along an ideal reversible path through the same state space. Entropy generation models for various classes of systems—thermal, externally loaded, internally reactive, open and closed—are developed via selection of suitable thermodynamic potentials. Here we simplify thermodynamic principles to specify convenient and consistently accurate system governing equations and characterization models. The formulations introduce a new and universal Phenomenological Entropy Generation (PEG) theorem. The systems and methods presented—and demonstrated on frictional wear, grease degradation, battery charging and discharging, metal fatigue and pump flow—can be used for design, analysis, and support of diagnostic monitoring and optimization.
