Practical resolution of angle dependency of multigroup resonance cross sections using parametrized spectral superhomogenization factors

open access: yesNuclear Engineering and Technology, 2017
Based on the observation that ignoring the angle dependency of multigroup resonance cross sections within a fuel pellet would result in nontrivial underestimation of the spatial self-shielding of flux, a parametrized spectral superhomogenization (SPH ...

The Effect of Input Parameter Variation on the Accuracy of a Vanadium Redox Flow Battery Simulation Model

open access: yesBatteries, 2021
Accurately predicting battery behavior, while using low input data, is highly desirable in embedded simulation architectures like grid or integrated energy system analysis. Currently, the available vanadium redox flow battery (VRFB) models achieve highly

Generation of Lagrangian intermittency in turbulence by a self-similar mechanism

open access: yesNew Journal of Physics, 2013
Intermittency, i.e., extreme fluctuations at small scales, causes the deviation of turbulence statistics from Kolmogorov's 1941 theoretical predictions. Intermittency effects are especially strong for Lagrangian statistics.

Resonance enhancement of dark matter interactions: the case for early kinetic decoupling and velocity dependent resonance width

open access: yesJournal of High Energy Physics, 2017
Motivated by the possibility of enhancing dark matter (DM) self-scattering cross-section σ self , we have revisited the issue of DM annihilation through a Breit-Wigner resonance.
