Applications of the Smoothed Particle Hydrodynamics method
Smoothed Particle Hydrodynamics SPH is a meshless Lagrangian parti cle method for solving a system of hydrodynamic equations for compressible uids SPH is especially suited for problems with free boundaries a commonplace situation in as trophysics Rather than solving the equations on a grid the equations are solved at the positions of the so called particles each representing a mass packet with ...
متن کاملIntroducing a Hybrid Radiative Transfer Method for Smoothed Particle Hydrodynamics
A new means of incorporating radiative transfer into smoothed particle hydrodynamics (SPH) is introduced, which builds on the success of two previous methods the polytropic cooling approximation as devised by Stamatellos et al (2007), and flux limited diffusion (e.g. Mayer et al 2007). This hybrid method preserves the strengths of its individual components, while removing the need for atmospher...
متن کاملIncompressible smoothed particle hydrodynamics
We present a smoothed particle hydrodynamic model for incompressible fluids. As opposed to solving a pressure Poisson equation in order to get a divergence-free velocity field, here incompressibility is achieved by requiring as a kinematic constraint that the volume of the fluid particles is constant. We use Lagrangian multipliers to enforce this restriction. These Lagrange multipliers play the...
متن کاملSmoothed particle hydrodynamics
In this review the theory and application of Smoothed particle hydrodynamics (SPH) since its inception in 1977 are discussed. Emphasis is placed on the strengths and weaknesses, the analogy with particle dynamics and the numerous areas where SPH has been successfully applied. 0034-4885/05/081703+57$90.00 © 2005 IOP Publishing Ltd Printed in the UK 1703
متن کاملSmoothed Particle Hydrodynamics :
We investigate the core mass distribution (CMD) resulting from numerical models of turbulent fragmentation of molecular clouds. In particular we study its dependence on the sonic rms Mach numberMs. We analyze simulations withMs ranging from 1 to 15 to show that, asMs increases, the number of cores increases as well, while their average mass decreases. This stems from the fact that high Mach num...
