A distribution-free lattice Boltzmann method for compartmental reaction-diffusion systems with application to epidemic modelling
Alessandro De Rosis
We introduce a distribution-free lattice Boltzmann formulation for general compartmental reaction--diffusion systems arising in mathematical epidemiology. The proposed scheme, term…
Unstable magnetic reconnection self-generates turbulence
Nick Williams, Alessandro De Rosis, Alex Skillen
Magnetic reconnection and turbulence are deeply intertwined in magnetohydrodynamic flows, yet how reconnection self-generates turbulence remains unclear. Using an ensemble of high-…
A fluctuating lattice Boltzmann formulation based on orthogonal central moments
Alessandro De Rosis, Yang Zhou
Thermal fluctuations play a central role in fluid dynamics at mesoscopic scales and must be incorporated into numerical schemes in a manner consistent with statistical mechanics. I…
Recursive regularised lattice Boltzmann method for magnetohydrodynamics
Alessandro De Rosis
We present and test a recursive regularised lattice Boltzmann method for incompressible magnetohydrodynamic (MHD) flows. The approach is based on a double-distribution formulation,…
