Artificial viscosity in simulation of shock waves by smoothed particle hydrodynamics
M. Nejad-Asghar, A. R. Khesali, J. Soltani
The artificial viscosity is reconsidered in smoothed particle hydrodynamics to prevent inter-particle penetration, unwanted heating, and unphysical solutions. The coefficients in t…

Formation of Fluctuations in the Molecular Slab via Isobaric Thermal Instability
M. Nejad-Asghar
The frictional heating by ion-neutral drift is calculated and its effect on isobaric thermal instability is carried out. Ambipolar drift heating of one-dimensional self-gravitating…
