Molecular dissipation in the nonlinear eddy viscosity in the Navier-Stokes equations: modelling of accretion discs
Giuseppe Lanzafame
Physical damping, regarding the nonlinear Navier-Stokes viscous flow dynamics, refers to a tensorial turbulent dissipation term, attributed to adjacent moving macroscopic flow comp…
Implicit integrations for SPH in Semi-Lagrangian approach: application to the accretion disc modelling in a microquasar
G. Lanzafame
Current explicit integration techniques in fluid dynamics are deeply limited by the Courant-Friedrichs-Lewy condition of the time step progression, based on the adopted spatial res…
An approach for solving the boundary free edge difficulties in SPH modelling: application to a viscous accretion disc in close binaries
G. Lanzafame
In this work, we propose a SPH interpolating Kernel reformulation suitable also to treat free edge boundaries in the computational domain. Application to both inviscid and viscous…
An approach to the Riemann problem in the light of a reformulation of the state equation for SPH inviscid ideal flows: a highlight on spiral hydrodynamics in accretion discs
G. Lanzafame
In physically inviscid fluid dynamics, "shock capturing" methods adopt either an artificial viscosity contribution or an appropriate Riemann solver algorithm. These techniques are…
An approach to the Riemann problem for SPH inviscid ideal flows: consequences for the state equation
G. Lanzafame
In the non viscous fluid dynamics, Smooth Particle Hydrodynamics (SPH), as a free Lagrangian "shock capturing" method adopts either an artificial viscosity contribution or an appro…
