A random space-time birth particle method for 2d vortex equations with external field
(2008)
We consider incompressible 2d Navier-Stokes equations in the whole plane with external nonconservative forces fields. The initial data and external field are functions assumed to satisfy only slight integrability properties. ...
Wetting transitions displayed by persistent active particles
(2017)
A lattice model for active matter is studied numerically, showing that it displays wetting transitions between three distinctive phases when in contact with an impenetrable wall. The particles in the model move persistently, ...
Collisions of spinning massive particles in a schwarzschild background
(2016)
It is known that the center-of-mass energy of the collision of two massive particles following geodesics around a black hole presents a maximum. The maximum energy increases when the black hole is endowed with spin, and ...
An assessment of particle methods for approximating anisotropic dispersion
(2013)
We derive a smoothed particle hydrodynamics (SPH) approximation for anisotropic dispersion that only depends upon the first derivative of the kernel function and study its numerical properties. In addition, we compare the ...
