Interactively Simulating Fluid based on SPH and CUDA
In this paper, we propose a novel method of interactive fluid simulating based on SPH, and implement it on CUDA (Compute Unified Device Architecture). Firstly we use SPH (Smoothed Particle Hydrodynamics) theory to simulate the motion of fluids. Secondly we propose an interactive method between fluid and rigid objects. We treat the rigid objects as two different types, static one and dynamic one...
متن کاملSimulating three-dimensional turbulence with SPH
In this paper, we have investigated the ability of smoothed particle hydrodynamics (SPH) to simulate turbulent flows. It is well known that the standard method without corrections cannot predict the energy cascade of a turbulent flow. In the absence of viscosity, standard SPH simulations produce purely noisy particle motion and at finite viscosities the method overpredicts dissipation. As a rem...
متن کاملReal-time fluid simulation with adaptive SPH
We present a new adaptive model for real-time fluid simulation based on Smoothed Particle Hydrodynamics (SPH) framework. Unlike traditional time-consuming SPH methods, our model can simulate fluid at a considerably faster speed without losing realism. In our model, we first introduce the non-uniform particle system and propose a generalized distance field function which considers not only geome...
متن کاملSimulating Colliding Flows in SPH with Fractional Derivatives
We propose a new method based on the use of fractional differentiation for improving the efficiency and realism of simulations based on Smoothed Particle Hydrodynamics (SPH). SPH represents a popular particle-based approach for fluid simulation and a high number of particles is typically needed for achieving high quality results. However, as the number of simulated particles increases, the spee...
متن کاملConservative Level Set/Ghost Fluid Method for Simulating Primary Atomization
This paper presents a novel approach for simulating incompressible two-phase flows by combining a conservative level set technique and the ghost-fluid method. Following the ideas of Olsson and Kreiss (2005), the liquid-gas interface is localized using a hyperbolic tangent level set that is transported and reinitialized using fully conservative numerical schemes. Mass conservation issues are gre...
