摘　　要：提出一个通用的火焰模拟框架,通过前处理、火焰模拟和后处理三个阶段生成满足用户需求且真实感强的火焰动画。针对该模拟框架,给出一种有效解决方案。根据火焰的两相流特性以及流体湍流特性,提出火焰的湍流模型,在有限计算资源条件下生成细节丰富的高真实感火焰动画。实验结果表明,所提出的火焰模拟框架切实可行,能逼真模拟基本火焰现象以及在复杂曲线、曲面和蔓延规则约束下的火焰动画。This paper presented a general fire simulation frame including three stages： pre-processing, fire simulation and post-processing. In order to implement this fire animation frame, the corresponding solutions were provided to address the key issues in every stage. Based on the two-phase flow characteristics of fire and the performance of turbulence fluid, a turbulence model using limited computing resources was proposed to rich the flame details. The experimental results show the effectiveness of the proposed flame simulation frame which can generate not only the basic fire phenomena but also other fire animations under the control of complex curves or surfaces and spreading rules.
