Galactic cosmic ray modulation near the heliospheric current sheet

, 2014
Galactic cosmic rays (GCRs) are modulated by the heliospheric magnetic field (HMF) both over decadal time scales (due to long-term, global HMF variations), and over time scales of a few hours (associated with solar wind structures such as coronal mass ...

Hybrid solvers for reactor modelling: matrix-based and matrix-free approaches on voxel-dominated meshes

Frontiers in Nuclear Engineering
Simulating neutronics and thermal hydraulics within nuclear reactor cores is computationally intensive, not only because of the complexity of the governing equations but also because of the intricate geometries involved.

Benchmarking Geant4 for spallation neutron source calculations

, 2016
Geant4 is becoming increasingly used for radiation transport simulations of spallation neutron sources and related components. Historically, the code has seen little usage in this field and it is of general interest to investigate the suitability of ...

Adaptive discontinuous Galerkin methods for the neutron transport equation [PDF]

, 2014
In this thesis we study the neutron transport (Boltzmann transport equation) which is used to model the movement of neutrons inside a nuclear reactor. More specifically we consider the mono-energetic, time independent neutron transport equation.
