Resolving the high redshift Lyman-α forest in smoothed particle hydrodynamics simulations
We use a large set of cosmological smoothed particle hydrodynamics (SPH) simulations to examine the effect of mass resolution and box size on synthetic Lyα forest spectra at 2 ≤ z ≤ 5. The mass resolution requirements for the convergence of the mean Lyα flux and flux power spectrum at z = 5 are significantly stricter than at lower redshift. This is because transmission in the high redshift Lyα ...
متن کاملResolving mixing in Smoothed Particle Hydrodynamics
Standard formulations of smoothed particle hydrodynamics (SPH) are unable to resolve mixing at fluid boundaries. We use an error and stability analysis of the generalized SPH equations of motion to prove that this is due to two distinct problems. The first is a leading order error in the momentum equation. This should decrease with an increasing neighbour number, but does not because numerical ...
متن کاملIncompressible 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 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...
