Prediction of Fatigue Crack Growth Rate Based on Entropy Generation [PDF]
Entropy, 2019 This paper presents the assessment of fatigue crack growth rate for dual-phase steel under spectrum loading based on entropy generation. According to the second law of thermodynamics, fatigue crack growth is related to entropy gain because of its irreversibility.

Teaching Fluid Mechanics and Thermodynamics Simultaneously through Pipeline Flow Experiments
Fluids, 2019 Entropy and entropy generation are abstract and illusive concepts for undergraduate students. In general, students find it difficult to visualize entropy generation in real (irreversible) processes, especially at a mechanistic level.

Continuum Breakdown Parameter Based on Entropy Generation Rates [PDF]
41st Aerospace Sciences Meeting and Exhibit, 2003 The dimensionless ratio of the mean free path to a reference length scale typically quantifies the extent to which the continuum assumption in fluid flow dynamics breaks down. However, ambiguity exists in the choice of an appropriate length scale and some researchers have suggested a local parameter, like the Knudsen number, for quantifying continuum ...

Constructal Optimizations of Line-to-Line Vascular Channels with Turbulent Convection Heat Transfer
Entropy, 2022 The multi-scale line-to-line vascular channels (LVCs) widely exist in nature because of their excellent transmission characteristics. In this paper, models of LVCs with turbulent convection heat transfer are established.

Predictive Complexity and Generalized Entropy Rate of Stationary Ergodic Processes [PDF]
, 2012 In the online prediction framework, we use generalized entropy of to study the loss rate of predictors when outcomes are drawn according to stationary ergodic distributions over the binary alphabet. We show that the notion of generalized entropy of a regular game \cite{KVV04} is well-defined for stationary ergodic distributions.
