Entropy Generation Rates in Two-Dimensional Rayleigh–Taylor Turbulence Mixing [PDF]
Entropy, 2018 Entropy generation rates in two-dimensional Rayleigh–Taylor (RT) turbulence mixing are investigated by numerical calculation. We mainly focus on the behavior of thermal entropy generation and viscous entropy generation of global quantities with ...

Unsteady Volumetric Entropy Generation Rate in Laminar Boundary Layers [PDF]
Entropy, 2006 The prediction of the entropy generation rate in laminar shear layers is treated as steady, even in the presence of high levels of free stream turbulence.

Effects of Convective Heating on Entropy Generation Rate in a Channel with Permeable Walls [PDF]
Entropy, 2013 This study deals with the combined effects of convective heating and suction/injection on the entropy generation rate in a steady flow of an incompressible viscous fluid through a channel with permeable walls.

Self-Organization, Entropy Generation Rate, and Boundary Defects: A Control Volume Approach. [PDF]
Entropy (Basel), 2021 Self-organization that leads to the discontinuous emergence of optimized new patterns is related to entropy generation and the export of entropy. Compared to the original pattern that the new, self-organized pattern replaces, the new features could involve an abrupt change in the pattern-volume. There is no clear principle of pathway selection for self-

Minimization of entropy generation rate in methanol steam reforming reactor
Case Studies in Thermal EngineeringThe methanol steam reforming (MSR) reaction is a prospective method in hydrogen generation because of its operability and high conversion efficiency. Most of the current thermodynamic studies involving MSR use classical thermodynamic methods, while fewer

Entropy Generation Rate Minimization for Methanol Synthesis via a CO2 Hydrogenation Reactor. [PDF]
Entropy (Basel), 2019 The methanol synthesis via CO2 hydrogenation (MSCH) reaction is a useful CO2 utilization strategy, and this synthesis path has also been widely applied commercially for many years. In this work the performance of a MSCH reactor with the minimum entropy generation rate (EGR) as the objective function is optimized by using finite time thermodynamic and ...

Entropy Generation Rate in a Chemically Reacting System [PDF]
Journal of Energy Resources Technology, 1993 Abstract For a nonchemical-equilibrium state of an isolated system A that has r constituents with initial amounts na = {n1a, n2a, …, nra}, and that is subject to τ chemical reaction mechanisms, temperature, pressure, and chemical potentials cannot be defined.

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 ...
