Incompressible smoothed particle hydrodynamics simulations on free surface flows
The water wave generation by wave paddle and a freely falling rigid body are examined by using an Incompressible Smoothed Particle Hydrodynamics (ISPH). In the current ISPH method, the pressure was evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure Poisson equation contains both of divergence free ve...
متن کاملUsing Smoothed Particle Hydrodynamics for Industrial Flow Simulations
Pictorial representation of the nine Fluent 5 benchmark test cases (see article on page 13) Editorial L'inauguration de la Swiss T1 du 23 août dernier à l'EPFL a démontré que l'utilisation d'un ordinateur parallèle basé sur une grappe constituée de composants standard du marché est une solution viable pour des calculs à haute performance. Les résultats obtenus par les différents utilisateurs su...

متن کاملChemical mixing in smoothed particle hydrodynamics simulations
We introduce a simple and efficient algorithm for diffusion in smoothed particle hydrodynamics (SPH) simulations and apply it to the problem of chemical mixing. Based on the concept of turbulent diffusion, we link the diffusivity of a pollutant to the local physical conditions and can thus resolve mixing in space and time. We apply our prescription to the evolution of an idealized supernova rem...
متن کاملCosmological Simulations with Adaptive Smoothed Particle Hydrodynamics
We summarize the ideas that led to the Adaptive Smoothed Particle Hydrodynamics (ASPH) algorithm, with anisotropic smoothing and shock-tracking. We then identify a serious new problem for SPH simulations with shocks and radiative cooling — false cooling — and discuss a possible solution based on the shock-tracking ability of ASPH.
