A comprehensive approach to understanding irreversibility in a turbojet
Propulsion and Power Research, 2018 Regarding interest in and concerns about high efficiency in recent times, an irreversibility assessment of energy conversion systems is significant. Turbojets, a type of energy conversion system, are widely used to provide thrust for aerial vehicles ...

Scaling Analysis of Time-Reversal Asymmetries in Fully Developed Turbulence
Fractal and Fractional, 2023 In fully developed turbulence, there is a flux of energy from large to small scales in the inertial range until the dissipation at small scales. It is associated with irreversibility, i.e., a breaking of the time reversal symmetry.

Coherent structures at the origin of time irreversibility in wall turbulence
Communications Physics, 2023 Time irreversibility is a distinctive feature of non-equilibrium phenomena such as turbulent flows, where irreversibility is mainly associated with an energy cascade process.

Randomness and Irreversiblity in Quantum Mechanics: A Worked Example for a Statistical Theory
Entropy, 2021 The randomness of some irreversible quantum phenomena is a central question because irreversible phenomena break quantum coherence and thus yield an irreversible loss of information.

Interpretation of Entropy Calculations in Energy Conversion Systems
Energies, 2021 Often, second law-based studies present merely entropy calculations without demonstrating how and whether such calculations may be beneficial. Entropy generation is commonly viewed as lost work or sometimes a source of thermodynamic losses.

Algorithmic Approaches for Assessing Irreversibility in Time Series: Review and Comparison
Entropy, 2021 The assessment of time irreversibility, i.e., of the lack of invariance of the statistical properties of a system under the operation of time reversal, is a topic steadily gaining attention within the research community.
