浸没边界格子Boltzmann方法的改进及转动圆柱绕流模拟
Improved immersed boundary lattice Boltzmann method and simulation of flow over rotating cylinder
摘要
Abstract
Based on Suzuki's immersed boundary lattice Boltzmann method, an improved approach is pro⁃posed. By adopting the force model of the lattice Boltzmann method and improving the technique of fluid structure interaction force calculation, the process of calculating the force of fluid structure interaction is simplified. Moreover,its calculation time is over 50%shorter than that of the original method, which means that efficiency is greatly improved. Based on the improved method, such features as lift coefficient, drag co⁃efficient,pressure coefficient and flow field are discussed under different conditions of flow over a rotating cylinder. Compared with the related results, this new improved method is shown to be accurate and reliable.关键词
