Abstract
AbstractTurbulent wake is crucial for the visually appealing effects of liquid. Unfortunately, it is challenging to realistically simulate this phenomenon with ring‐shaped vortical structures. To tackle this issue, we propose a filament‐based turbulent wake synthesis method for realistically simulating the turbulent wake with ring‐shaped vortical structures. The filaments are sampled at the separation points on the obstacle surface and emitted into the liquid flow to generate structured turbulent wake. Besides, the surface tension model is incorporated to generate natural turbulent wake diffusion visual effects in liquid by the anticurvature effects. The proposed approach can realistically and effectively synthesize the turbulent wake with ring‐shaped vortical structures and make it diffuse naturally. The experimental results demonstrate that our method outperforms than the vortex particle‐based method in synthesizing appealing turbulent wake.
