An Entropy Generation Rate Model for Tropospheric Behavior That Includes Cloud Evolution [PDF]
Entropy, 2023 A postulate that relates global warming to higher entropy generation rate demand in the tropospheric is offered and tested. This article introduces a low-complexity model to calculate the entropy generation rate required in the troposphere.

Entropy Generation during Head-On Interaction of Premixed Flames with Inert Walls within Turbulent Boundary Layers [PDF]
Entropy, 2022 The statistical behaviours of different entropy generation mechanisms in the head-on interaction of turbulent premixed flames with a chemically inert wall within turbulent boundary layers have been analysed using Direct Numerical Simulation data.

Methods to Calculate Entropy Generation. [PDF]
Entropy (Basel)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 ...

Generalized weighted permutation entropy
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022 A novel heuristic approach is proposed here for time series data analysis, dubbed Generalized weighted permutation entropy, which amalgamates and generalizes beyond their original scope two well established data analysis methods: Permutation entropy and Weighted permutation entropy.

Composability and generalized entropy [PDF]
Physics Letters A, 1999 We address in this paper how tightly the composability nature of systems: $S_{A+B} = (S_A, S_B)$ constrains definition of generalized entropies and investigate explicitly the composability in some ansatz of the entropy form.

Analysis of Entropy Generation and Potential Inhibition in an Aeroengine System Environment
International Journal of Aerospace Engineering, 2022 From a system perspective, the entropy generation of an aeroengine is directly related to the thermal efficiency when the Brayton cycle pressure ratio and maximum temperature remain constant.
