Entropy generation minimization for CO2 hydrogenation to light olefins
Energy, 2018Abstract An optimization model is established for the reaction process of CO2 hydrogenation to light olefins in a fixed-bed tubular reactor based on finite time thermodynamics or entropy generation minimization theory. In the present study, the specific generation rate (entropy generation rate averaged by the production rate of the target product) is

Production optimization of hydrocarbon reservoirs by entropy generation minimization
Journal of Natural Gas Science and Engineering, 2020 Abstract Reservoir entropy generation has a significant role in production cycles of a hydrocarbon reservoir. During production, entropy generation characterizes the irreversible fluid energy losses. This paper aims to develop a new production strategy that minimizes the entropy production to improve operational efficiencies.

Resolving the Generalized Bas-Relief Ambiguity by Entropy Minimization
2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007It 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
2022This 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, 2011A 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 (EGM) in magneto peristalsis with variable properties
Computer Methods and Programs in Biomedicine, 2020This article featuring the peristaltic transport of viscous material with variable properties (i.e. temperature dependent viscosity and thermal conductivity) through curved configuration. Fluid saturating through porous channel walls of uniform space. Entropy generation consideration here is to analyze irreversibility aspects. Channel boundaries retain
