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 ...

Analysis of Effect of Heat Pipe Parameters in Minimising the Entropy Generation Rate [PDF]
Journal of Thermodynamics, 2016 Heat transfer and fluid flow in the heat pipe system result in thermodynamic irreversibility generating entropy. The minimum entropy generation principle can be used for optimum design of flat heat pipe. The objective of the present work is to minimise the total entropy generation rate as the objective function with different parameters of the flat ...

Entropy generation in condensation in the presence of high concentrations of noncondensable gases [PDF]
, 2012 The physical mechanisms of entropy generation in a condenser with high fractions of noncondensable gases are examined using scaling and boundary layer techniques, with the aim of defining a criterion for minimum entropy generation rate that is useful in ...

A mathematical model for entropy generation in a Powell-Eyring nanofluid flow in a porous channel
Heliyon, 2019 The continuous generation of entropy leads to exergy destruction which reduces the performance of a physical system. Hence, entropy minimization becomes necessary.
