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…
Investigating thermal evolution of the self-gravitating one dimensional molecular cloud by smoothed particle hydrodynamics
Mohsen Nejad-Asghar, Diego Molteni
The heating of the ion-neutral (or ambipolar) diffusion may affect the thermal phases of the molecular clouds. We present an investigation on the effect of this heating mechanism i…
Smoothed Particle Hydrodynamics in Thermal Phases of a One Dimensional Molecular Cloud
M. Nejad-Asghar, D. Molteni
We present an investigation on effect of the ion-neutral (or ambipolar) diffusion heating rate on thermal phases of a molecular cloud. We use the modeling of ambipolar diffusion wi…
Modeling fragmentation of the self-gravitating molecular layer by smoothed particle hydrodynamics
M. Nejad-Asghar, D. Molteni
We revisit the modeling of ion-neutral (or ambipolar) diffusion with two fluid smoothed particle hydrodynamics, as discussed by Hosking & Whitworth. Some parts of the technique are…
Bending Instability of an Accretion Disc Around a Black Hole
D. Molteni, K. Acharya, Oleg Kuznetsov +2
We demonstrate that generically an accretion disk around a compact object could have a new type of instability in that the accretion flow need not be symmetric with respect to the…
Why Canonical Disks Cannot Produce Advection Dominated Flows
D. Molteni, G. Gerardi, M. A. Valenza
Using simple arguments we show that the canonical thin keplerian accretion disks cannot smoothly match any plain advection dominated flow (ADAF) model. By 'plain' ADAF model we mea…
