Hydrodynamic simulations of self-phoretic microswimmers [PDF]
Soft Matter, 2014 A mesoscopic hydrodynamic model to simulate synthetic self-propelled Janus particles which is thermophoretically or diffusiophoretically driven is here developed. We first propose a model for a passive colloidal sphere which reproduces the correct rotational dynamics together with strong phoretic effect.

Hydrodynamical simulations and similarity relations for eruptive mass-loss from massive stars [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Motivated by the eruptive mass loss inferred from Luminous Blue Variable (LBV) stars, we present 1D hydrodynamical simulations of the response from sudden energy injection into the interior of a very massive ($100 \, M_\odot$) star.

On the origin of non self-gravitating filaments in the ISM [PDF]
, 2013 {Filaments are ubiquitous in the interstellar medium as recently emphasized by Herschel, yet their physical origin remains elusive} {It is therefore important to understand the physics of molecular clouds to investigate how filaments form and what is the

Hydrodynamical Simulations of the Lyman Alpha Forest: Model Comparisons [PDF]
, 1999 We investigate the properties of the Lyman alpha forest as predicted by numerical simulations for a range of currently viable cosmological models. This is done in order to understand the dependencies of the forest on cosmological parameters.

Full hydrodynamic simulation of GaAs MESFETs [PDF]
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2004 AbstractA finite difference upwind discretization scheme in two dimensions is presented in detail for the transient simulation of the highly coupled non‐linear partial differential equations of the full hydrodynamic model, providing thereby a practical engineering tool for improved charge carrier transport simulations at high electric fields and ...

Coupling 1D stellar evolution with 3D-hydrodynamical simulations on-the-fly II: stellar evolution and asteroseismic applications [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Models of stellar structure and evolution are an indispensable tool in astrophysics, yet they are known to incorrectly reproduce the outer convective layers of stars. In the first paper of this series, we presented a novel procedure to include the mean

Numerical convergence of hydrodynamical simulations of galaxy formation: the abundance and internal structure of galaxies and their cold dark matter haloes [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We address the issue of numerical convergence in cosmological smoothed particle hydrodynamics simulations using a suite of runs drawn from the eagle project.

Numerical Simulations of Jets from Active Galactic Nuclei
Galaxies, 2019 Numerical simulations have been playing a crucial role in the understanding of jets from active galactic nuclei (AGN) since the advent of the first theoretical models for the inflation of giant double radio galaxies by continuous injection in the late ...

A Self-gravity Module for the PLUTO Code
The Astrophysical Journal Supplement Series, 2023 We present a novel implementation of an iterative solver for the solution of Poisson’s equation in the PLUTO code for astrophysical fluid dynamics. Our solver relies on a relaxation method in which convergence is sought as the steady-state solution of a ...

Galaxies that Shine: radiation-hydrodynamical simulations of disk galaxies [PDF]
, 2015 Radiation feedback is typically implemented using subgrid recipes in hydrodynamical simulations of galaxies. Very little work has so far been performed using radiation-hydrodynamics (RHD), and there is no consensus on the importance of radiation feedback
