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.

Entropy generation minimization in turbulent mixed convection flows
International Communications in Heat and Mass Transfer, 2007Abstract This paper reports the results of a numerical investigation of turbulent mixed convection from a symmetrically heated vertical channel, bathed by a steady upward flow of cold air. The computations have been performed using FLUENT 6.2 by employing the k–e model for turbulence with enhanced wall treatment.

Optimization of microchannel heat sinks using entropy generation minimization method
Twenty-Second Annual IEEE Semiconductor Thermal Measurement And Management Symposium, 2006In this study, an entropy generation minimization (EGM) procedure is employed to optimize the overall performance of microchannel heat sinks. This allows the combined effects of thermal resistance and pressure drop to be assessed simultaneously as the heat sink interacts with the surrounding flow field.

◾ Entropy Generation Minimization in Nanofluid Flow
2015Extensive 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.

Production optimization of hydrocarbon reservoirs by entropy generation minimization
Journal of Natural Gas Science and Engineering, 2020Abstract 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.

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

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.

Eyring–Powell nanofluid flow with nonlinear mixed convection: Entropy generation minimization
Computer Methods and Programs in Biomedicine, 2020Entropy is the amount of energy which is lost during any irreversible process. Here our main focus is that how can we reduce this energy loss to enhance the capability of our system. Blood is an example of Eyring-Powell fluid. Many strategies are used to rise the capacity of heat transport.
