Entropy generation analysis in flow of thixotropic nanofluid
International Journal of Numerical Methods for Heat & Fluid Flow, 2019Purpose The purpose of this paper is to address entropy generation in flow of thixotropic nonlinear radiative nanoliquid over a variable stretching surface with impacts of inclined magnetic field, Joule heating, viscous dissipation, heat source/sink and chemical reaction. Characteristics of nanofluid are described by Brownian motion and thermophoresis

Entropy generation analysis of an adsorption cooling cycle
International Journal of Heat and Mass Transfer, 2013Abstract This paper discusses the analysis of an adsorption (AD) chiller using system entropy generation as a thermodynamic framework for evaluating total dissipative losses that occurred in a batch-operated AD cycle. The study focuses on an adsorption cycle operating at heat source temperatures ranging from 60 to 85 °C, whilst the chilled water ...

Entropy Generation Analysis for Nanofluid Flow in Microchannels
Journal of Heat Transfer, 2010Employing a validated computer simulation model, entropy generation is analyzed in trapezoidal microchannels for steady laminar flow of pure water and CuO-water nanofluids. Focusing on microchannel heat sink applications, local and volumetric entropy rates caused by frictional and thermal effects are computed for different coolants, inlet temperatures,

Analysis of Entropy Generation and Thermal Stability in a Slab
Journal of Thermophysics and Heat Transfer, 2010This study investigates the inherent irreversibility in a rectangular slab with temperature-dependent internal heating. It is assumed that the slab external surfaces are subjected to asymmetric heat exchange with the surrounding medium. The simplified governing equation for energy balance in Cartesian coordinates is solved analytically and expedites to

Entropy generation analysis of magnetohydrodynamic induction devices
Journal of Physics D: Applied Physics, 1999Magnetohydrodynamic (MHD) induction devices such as electromagnetic pumps or electric generators are analysed within the approach of entropy generation. The flow of an electrically-conducting incompressible fluid in an MHD induction machine is described through the well known Hartmann model.

Entropy generation analysis of laser evaporative heating
Exergy, An International Journal, 2002Abstract Laser pulse heating offers considerable advantages over the conventional heating methods. This is due to their operational precision and local treatment. In order to improve the energy efficient processing, entropy analysis of the laser heating is essential.

General Entropy Production Based on Dynamical Analysis
2015The classical expression for entropy production is a bilinear product of generalized forces and fluxes. The combination of the Cattaneo-Vernotte model with the classical entropy expression gives a non-quadratic form, which needs to be mended to avoid the paradox of negative entropy production.
