Entropy Generation Due to Laminar Incompressible Forced Convection Flow Through Parallel-Plates Microchannel

Entropy, 2004
: The entropy generation due to steady laminar forced convection fluid flow through parallel plates microchannel is investigated numerically. The effect of Knudsen, Reynolds, Prandtl, Eckert numbers and the nondimensional temperature difference on ...

Simulation of Entropy Generation under Stall Conditions in a Centrifugal Fan

Entropy, 2014
Rotating stalls are generally the first instability met in turbomachinery, before surges. This 3D phenomenon is characterized by one or more stalled flow cells which rotate at a fraction of the impeller speed. The goal of the present work is to shed some

Spin-related Cu-Co pair to increase electrochemical ammonia generation on high-entropy oxides

Nature Communications
Electrochemical conversion of nitrate into ammonia offers a method for mitigating nitrate pollution in water. Here the authors report the electrochemical nitrate-to-ammonia conversion using high-entropy oxide Mg_0.2Co_0.2Ni_0.2Cu_0.2Zn_0.2O and find that

Entropy production and lost work for irreversible processes

, 2006
In this paper we analyse in depth the Lost Work in an irreversible process (i.e. IRREV REV Lost ) W =W -W . This quantity is also called ‘degraded energy’ or ‘Energy unavailable to do work’. Usually in textbooks one can find the relation Lost U W o TDS .
