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.

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 ...

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.

Optimization of regenerator operating parameters and thermal insulation construction for rotary regenerative thermal oxidizer (r-RTO) based on thermal-fluid coupling method and quadratic regression model

open access: yesCase Studies in Thermal Engineering, 2022
Rotary regenerative oxidiser (r-RTO), an effective VOCs treatment equipment, needs to be operated for a long time under actual working conditions, resulting in excessive temperatures on the outer wall of the r-RTO furnace, which causes production ...
