A Class of Reduced-Order Regenerator Models

open access: yesEnergies, 2021
We present a novel class of reduced-order regenerator models that is based on Endoreversible Thermodynamics. The models rest upon the idea of an internally reversible (perfect) regenerator, even though they are not limited to the reversible description ...

From signal processing of telecommunication signals to high pulse energy lasers: the Mamyshev regenerator case [PDF]

open access: yesNanophotonics
We look back at many challenges as well as unexpected successes encountered by the Mamyshev optical regenerator, which combines spectral broadening from self-phase modulation followed by offset bandpass filtering.

To regenerate or not to regenerate: Vertebrate model organisms of regeneration‐competency and ‐incompetency [PDF]

open access: yesWound Repair and Regeneration, 2022
AbstractWhy only certain species can regenerate their appendages (e.g. tails and limbs) remains one of the biggest mysteries of nature. Unlike anuran tadpoles and salamanders, humans and other mammals cannot regenerate their limbs, but can only regrow lost digit tips under specific circumstances.

Gas Turbine Tubular Coilpipes Regenerators Optimized According to the Minimum Mass Criterion [PDF]

open access: yesProblems of the Regional Energetics, 2021
The aim of this work is to determine the effect of the elements, which do not participate in heat transfer, on the mass of the regenerator of a gas turbine plant X, as well as to define the re-strictions that are imposed on the regenerator design based ...

Regeneration inducers in limb regeneration [PDF]

open access: yesDevelopment, Growth & Differentiation, 2015
Limb regeneration ability, which can be observed in amphibians, has been investigated as a representative phenomenon of organ regeneration. Recently, an alternative experimental system called the accessory limb model was developed to investigate early regulation of amphibian limb regeneration.

Theoretical study of a Rotary Regenerator in a Thermal Power Plant [PDF]

open access: yesKirkuk Journal of Science, 2010
In this research, the rotary regenerator is analyzed by solving government differential equations of heat transfer in the regenerator analytically and comparing the results with the designed data in order to study the performance of the rotary ...

A Three-dimensional CFD Study on Multiphase Flow in an FCC Regenerator Integrated with Oxy-combustion [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
A vital process for converting heavy petroleum productions is Fluid Catalytic Cracking (FCC). As a major source of CO2 emissions, the regenerator reactor in the FCC unit accounts for about 20-35% of the refinery's total emissions.

Analytical Solution of Heat Transfer Performance of Grid Regenerator in Inverse Stirling Cycle

open access: yesEnergies, 2022
The regenerator plays an extremely important role in the Stirling circulation. A grid regenerator can be used for inverse Stirling machines at room temperature due to its low flow resistance.
