简化物理模型的卡通火焰模拟
Cartoon flame simulation of simplified physical model
摘要
Abstract
A simplified fluid physical model is introduced and a method of flame cartoon style is realized. Through simplifying the external force,this method can omit the calculation of the flame's buoyancy, and use the best numerical value derived form the experiments instead of the buoyancy in each temperature layer directly. Afterwards, the advection, diffusion and projection are calculated after the Helmholtz-Hodge decomposition. The whole solution is stable.Because of reducing the calculation of temperature's influence on external force and the calculation of the cyclone, the speed obtained from this method has been improved greatly and a cartoon flame is realized effectively.关键词
