Entropy Generation Minimization of Two-Phase Flow Irreversibilities in Hydrocarbon Reservoirs

open access: yesEnergies, 2023
The efficient use of available energy in hydrocarbon extraction processes is essential to reducing overall emissions in the petroleum industry. The inefficient design of an extraction process leads to higher emissions per unit mass of hydrocarbon ...

Entropy Generation Minimization for Energy-Efficient Desalination [PDF]

open access: yesVolume 6B: Energy, 2018
Desalination systems can be conceptualized as power cycles, in which the useful work output is the work of separation of fresh water from saline water. In this framing, thermodynamic analysis provides powerful tools for raising energy efficiency. This paper discusses the use of entropy generation minimization for a spectrum of desalination systems ...

Entropy Generation via Ohmic Heating and Hall Current in Peristaltically-Flowing Carreau Fluid

open access: yesEntropy, 2019
The core objective of the present study is to examine entropy generation minimization via Hall current and Ohmic heating. Carreau fluid considerations interpret the unavailability of systems’ thermal energy (for mechanical work).

Entropy generation rate minimization for sulfur trioxide decomposition membrane reactor

open access: yesEnergy Reports, 2022
Sulfuric acid decomposition is the critical reaction in sulfur-iodide thermochemical cycle to produce oxygen. Sulfuric acid can decompose spontaneously into sulfur trioxide (SO3) and water, and SO3 continues to decompose into oxygen and sulfur dioxide ...
