Teach Second Law of Thermodynamics via Analysis of Flow through Packed Beds and Consolidated Porous Media

Fluids, 2019
The second law of thermodynamics is indispensable in engineering applications. It allows us to determine if a given process is feasible or not, and if the given process is feasible, how efficient or inefficient is the process.

Entropy generation and jet engine optimization

, 2010
In 2009, it was shown that, with an original approach to hydrodynamic cavitation, a phenomenological model was realized in order to compute some of the physical parameters needed for the design of the most common technological applications (turbo ...

Paths and stochastic order in open systems

, 2011
The principle of maximum irreversible is proved to be a consequence of a stochastic order of the paths inside the phase space; indeed, the system evolves on the greatest path in the stochastic order.

Extremal Quantum Correlations: Experimental Study with Two-qubit States

, 2011
We explore experimentally the space of two-qubit quantum correlated mixed states, including frontier ones as defined by the use of quantum discord and von Neumann entropy. Our experimental setup is flexible enough to allow for the high-quality generation

Entropy generation during fluid flow in sharp edge wavy channels with horizontal pitch

Advances in Mechanical Engineering, 2016
In this study, the volumetric entropy generation rate is analyzed in sharp edge wavy channels. A two-dimensional steadily developing fluid flow is considered. Air is considered as the working fluid in the numerical analysis.

Effect of Incidence Angle on Entropy Generation in the Boundary Layers on the Blade Suction Surface in a Compressor Cascade

Entropy, 2019
The entropy generation that occurs within boundary layers over a C4 blade at a Reynolds number of 24,000 and incidence angles (i) of 0°, 2.5°, 5°, 7.5°, and 10° are investigated experimentally using a particle image velocimetry ...

Tracing the classical molecular nature of entropy generation

AIP Advances
The second law of thermodynamics and the concept of positive entropy generation are analyzed following classical statistical mechanics methods. Previously, using the generalized Boltzmann–Gibbs entropy and its associated general entropy conservation ...

Second law efficiency and thermal entropy generation of 30:70% of glycerol + water based SiO2 nanofluids in a thermosyphon flat plate collector: Experimental and Bayesian artificial neural network algorithm

International Journal of Thermofluids
This research examines the thermal entropy generation, frictional entropy generation, entropy generation number, and energy efficiency, which were experimentally assessed for a flat plate collector functioning under thermosyphon conditions utilizing a ...
