Numerical Chebyshev finite difference examination of Lorentz force effect on a dissipative flow with variable thermal conductivity and magnetic heating: Entropy generation minimization

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2022
This work presents the computational analysis of entropy generation minimization in a dissipative flow of viscous fluid. The flow is produced by a non‐linearly elastic surface under the influence of the variable magnetic field.

Resolving the Generalized Bas-Relief Ambiguity by Entropy Minimization

2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007
It is well known in the photometric stereo literature that uncalibrated photometric stereo, where light source strength and direction are unknown, can recover the surface geometry of a Lambertian object up to a 3-parameter linear transform known as the generalized bas relief (GBR) ambiguity.

Entropy Generation Minimization in a Vertical Porous Channel

2022
This chapter is mainly focused on the minimization of the total entropy generation in a thermodynamic system, which concerns the heating of water when it passes through a saturated porous media. The heating process is assumed by an array of heating tubes immerged on the porous media and perpendicular to the water flow direction.

Minimization of entropy generation in flat heat pipe

International Journal of Heat and Mass Transfer, 2011
A thermodynamic model of flat heat pipe is developed based on the laws of thermodynamics. Major reasons for entropy generation, which is considered as a significant parameter on heat pipe performance, are temperature difference between hot and cold reservoirs, frictional losses in the flow of working fluid, and vapor temperature and pressure drop along

Entropy Generation Minimization in Nanofluid Flow

2015
Extensive studies can be found in the literature on the development of nanofluids and improvements of their thermofluid characteristics both theoretically and experimentally. On the contrary, most of the studies on nanofluids have been conducted from the first law of thermodynamics perspective.
