Fluid simulations based on Smoothed Particle Hydrodynamics (SPH) have been widely used for generating complex motion of fluid.However,implementation of searching particle neighbors on graphics processing unit (GPU) can not be satisfied till now.In this paper, we present a new grid-based neighbor search method on GPU for GPU-based SPH fluid simulation.Using this new GPU-based neighbor search technique...
In this paper, a particle-based simulation method for the immiscible liquid-liquid interaction is proposed. Through establishing an interfacial tension model for multiple liquids and using the essential method of the Smoothed Particle Hydrodynamics, the immiscible effects in the interaction simulation for multiple liquids can be embodied realistically. The experimental results verify the validity...
We present a novel method using particle importance to accelerate the traditional smoothed particle hydrodynamics based fluid simulation. Reynolds number and vorticity are exploited as the new criteria to evaluate the importance for each particle. If a particle is unimportant, its current acceleration and velocity are used to update values in the next time step with the complex state updating step...
Efficient numerical techniques developed in the field of computer graphics are able to simulate compellingly realistic simulations of interactions between solids and fluids. These techniques are less used for engineering applications due to errors inherent in the systemic approximations. The errors, manifesting as excessive damping, are expected to change the nature of steady-state fields and nullify...
