【Abstract】 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.更多还原
