FTIR Analysis Method for Purity Analysis of Gaseous UF6 at Low Pressure

open access: yesJournal of Isotopes, 2023
In order to establish a method for quantitative analysis of the purity of gaseous Uranium hexafluoride using Fourier infrared spectroscopy under low pressure, the absorption peak at 1 150 cm-1 was selected as the characteristic absorption peak for ...

FP-TES: Fluidization Based Particle Thermal Energy Storage, Part II: Experimental Investigations

open access: yesEnergies, 2020
In recent years, the fight against global warming and therefore CO2 reduction have become the most important issue for humanity. As a result, volatile sources of energy—like wind and solar power—are penetrating the electrical grid and therefore an ...

Assessing and Modelling the Interactions of Instrumented Particles with Bed Surface at Low Transport Conditions

open access: yesApplied Sciences, 2021
Sediment transport at near threshold to low transport stages (below the continuous transport) can still be affected by flow turbulence and its dynamics can benefit from further comprehensive studies. This study uses an instrumented particle embedded with

An Introduction to Particle Acceleration in Shearing Flows

open access: yesGalaxies, 2019
Shear flows are ubiquitously present in space and astrophysical plasmas. This paper highlights the central idea of the non-thermal acceleration of charged particles in shearing flows and reviews some of the recent developments.

Surrogate Modelling for High-speed Rotating Flow Fields Based on Multi-fidelity Data Fusion

open access: yesJournal of Isotopes
High-speed rotating flow fields play a pivotal role in the mechanical systems used for stable heavy isotopes. The high dimensional design space of such complex rotating machinery is characterized by strong nonlinearity and substantial parameter coupling.

A Study of Particle Transport in Young Pulsar Wind Nebulae

open access: yes, 2023
The broadband emission of numerous pulsar wind nebula (PWNe) in our Galaxy can be well described by synchrotron radiation and inverse Compton scattering from relativistic particles, specifically electrons and positrons.

Particle Transport within the Pulsar Wind Nebula HESS J1825-137 [PDF]

open access: yes, 2018
International audienceContext. We present a detailed view of the pulsar wind nebula (PWN) HESS J1825–137. We aim to constrain the mechanisms dominating the particle transport within the nebula, accounting for its anomalously large size and spectral ...
