基于动态Smagorinsky-MRT-LBM的圆柱绕流湍流研究
Numerical Simulation of Turbulent Flow Around Cylinder Based on Dynamic Smagorinsky-MRT-LBM
摘要
Abstract
Applies multiple relaxation lattice Boltzmann and large eddy simulation of dynamic Smagorinsky model for simulating turbulent flow around a cylinder, and researches periodic change of turbulent vortex flow around a cylinder under differentRe 300~10 000. The research shows that: the calculated Strouhal numberand the drag coefficient are consis-tent with the published experimental results and the finite element simulation results, indicating that the method is reason-able for simulating turbulent flow of different Reynolds number .关键词
