摘    要:提出基于平滑粒子流体力学的自由界面流体模拟方法,采用了范德瓦尔斯方程与粒子间短距离排斥力和长距离吸引力作用的表面张力,设计出基于GPU的粒子泼溅算法。渲染算法完全消除了时间离散假象,具有交互式的高质量渲染效果。与传统拉格朗日算法相比,该方法具有简化的表面张力模型,快速的渲染方式,减小了运算的复杂性,有效提高了系统的运行速度。

关 键 词:GPU  纳维-斯托克斯方程  拉格朗日法  平滑粒子流体力学  表面张力  粒子泼溅

Abstract:An approach based on smoothed particle hydrodynamics to simulate fluids with free surfaces was proposed, while surface tension was modeled by using Van der Waals equation of state with a combination of short-range repulsive and longer-range attractive interactions between fluid particles, finally a GPU-based particle splatting algorithm was designed for rendering. This approach completely avoids the temporal discretization artifacts, which results in the interactive rendering effects with high quality. In contrast to traditional Lagrangian approaches, this method uses the simplified surface tension model with fast rendering algorithm, reduces the complexity of the simulation and efficiently advances the run-time speed.
