Smoothed Particles Hydrodynamics numerical simulations of droplets walking on viscous vibrating liquid
Diego Molteni, Enrico Vitanza, Onofrio Rosario Battaglia
We study the phenomenon of the "walking droplet", by means of numerical fluid dynamics simulations using the Smoothed Particle Hydrodynamics numerical method. This phenomenon occur…

Simple absorbing boundary conditions for wave simulations with Smoothed Particle Hydrodynamics
Molteni Diego, Rosario Grammauta, Enrico Vitanza
We study and implement a simple method, based on the Perfectly Matched Layer approach, to treat non reflecting boundary conditions with the Smoothed Particles Hydrodynamics numeric…

A simple model of radiative emission in M87
E. Vitanza, V. Teresi, D. Molteni +1
We present a simple physical model of the central source emission in the M87 galaxy. It is well known that the observed X-ray luminosity from this galactic nucleus is much lower th…
