Full one-fluid dusty gas with multiple grain species in SPH
Mark Hutchison, Guillaume Laibe, Giovanni Tedeschi-Prades +5
We present a Smoothed Particle Hydrodynamics (SPH) implementation of the full one-fluid dusty gas algorithm for multiple dust species, generalising our previous terminal velocity a…

General Implicit Runge-Kutta Integrators for Multifluid Gas-Dust Aerodynamic Drag
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
The integration of aerodynamic drag is a fundamental step in simulating dust dynamics in hydrodynamical simulations. We propose a novel integration scheme, designed to be compatibl…

Modeling dust dynamics in OpenGadget3 -- I. SPH implementation of the One-Fluid model
Giovanni Tedeschi-Prades, Til Birnstiel, Klaus Dolag +2
Dust dynamics plays a critical role in astrophysical processes and has been modeled in hydrodynamical simulations using various approaches. Among particle-based methods like Smooth…
