Predicting Entropy Generation Rates in Transitional Boundary Layers Based on Intermittency
Journal of Turbomachinery, 2006 Prediction of thermodynamic loss in transitional boundary layers is typically based on time-averaged data only. This approach effectively ignores the intermittent nature of the transition region. In this work laminar and turbulent conditionally sampled boundary layer data for zero pressure gradient and accelerating transitional boundary layers have ...

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.

Journal of Materials Research and Technology, 2023 The objective of this present study is to use entropy generation to predict the fatigue life behaviour of magnesium alloy. As the energy dissipation rate directly correlates with material degradation and increases in temperature, the entropy generation ...

Thermal Analysis in Pipe Flow: Influence of Variable Viscosity on Entropy Generation
Entropy, 2004 : Flow through pipes and heating situations find wide applications in industry. Depending on the fluid properties, temperature field in the pipe changes. This in turn results in thermodynamic irreversibility in the flow system.

Hall Current and Joule Heating Effects on Flow of Couple Stress Fluid with Entropy Generation [PDF]
, 2018 In this work, an analytical study of the effects of Hall current and Joule heating on the entropy generation rate of couple stress fluid is performed. It is assumed that the applied pressure gradient induces fluid motion.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.
