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 کاملSmoothed Particle Hydrodynamics: Turbulence and MHD
In this paper we discuss recent applications of the Smoothed Particle Hydrodynamics (SPH) method to the simulation of supersonic turbulence in the interstellar medium, as well as giving an update on recent algorithmic developments in solving the equations of magnetohydrodynamics (MHD) in SPH. Using high resolution calculations (up to 134 million particles), we find excellent agreement with grid...
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 کاملSmoothed Particle Hydrodynamics in Flood Simulations
Water simulation and water effects are nowadays an evolving field. In recent years we have seen a big advance in fluid simulations. In this paper we present a method for flood simulations of cities and complex models. SPH method is used for the fluid simulation by which we gain less expensive computation than by using other known methods of simulation. Because of complex models, collision handl...
