- 摘要:
- 微下击暴流是一种突发性强且破坏力巨大的局地灾害性大风,为避免或减小其带来的灾害,研究了微下击暴流的风场结构特征,通过计算机流体力学建模软件CFD(computational fluid dynamics)建立出能反应风场内部特征的三维模型。基于单个微下击暴流的三维风场模型,提出并模拟了两个入口初速度不同的微下击暴流的三维风场模型,并研究了其相互影响。通过FLUENT软件的后处理器得到了速度云图、压力云图等产品。
- Abstract:
- The micro-burst is a kind of local catastrophic wind with strong suddenness and great destructive power. In order to avoid and reduce the disasters caused by it, this paper studied the characteristics of the wind field structure of the micro-burst. The computer fluid dynamics modeling software CFD(Computational fluid dynamics)established a three-dimensional model that can reflect the internal characteristics of the wind field. Based on the three-dimensional wind field model of a single micro-burst, this paper proposed and simulated the three-dimensional wind field model of two micro-bursts with different initial velocities at the entrance, meanwhile this paper studied their mutual influence. Through the post-processor of the FLUENT software, productd such as speed cloud graph and pressure cloud graph are obtained.
