Abstract :
We present a real-time wall-fountain simulation method based on the Smoothed Particle Hydrodynamics (SPH) framework. In our method, we use single layer particles projecting idea to deal with the characteristics of wall fountains such as "cling to the wall" and "sheet flow". For single layer particles, we derive the smoothing kernel functions in two-dimensional case. During the process of solving the particle density, the normalized density summation approach is used to improve the accuracy and incompressibility. To achieve more realistic motion, we also propose a wall-fluid interaction model. The achieved results show that our method can generate physically realistic wall-fountain animation in real-time on common PCs.
