摘　　要：以挑流泄洪为例,提出了基于泄洪水力学模型和粒子系统的虚拟泄洪水流运动的建模与实现方法,建立了坎前水舌运动、空中扩散射流、空中水舌碰撞以及水流跌水碰溅的粒子系统模型,实现了泄洪水流运动的场景逼真模拟,为直观分析高坝泄洪雾化问题提供了新的辅助手段。应用实例证明了该方法的有效性。Based on the physical mechanism of the phenomena of the flood discharge atomization, a method of visualization modeling and virtual reality for simulated flood discharge with ski-jump flow was proposed. And the simulated models of nappe motion before bucket, aerated jet trajectory, jet bump and droplets splashing were built using particle system technology. Then, a 3-D scene of ski-jump flow motion from high dam was realized. Therefore, a virtual environment for engineering design and analysis of flood discharge atomization was provided. An application example shows that the method is efficient and feasible.
