摘要
利用格子Boltzmann方法,分析缩放管结构、雷诺数等对管内流动状态的影响,得到了缩放管内湍流情况下流体阻力系数与滚压深度及节距间的关系式,从而实现了预测缩放管内湍流情况下流体的阻力系数.
Using the lattice Boltzmann method, the effects of the structure of converging-diverging tube and Reynolds number to the state of flow was analyzed. Then the relational expression among the flow resistance coefficient, rolling depth and the pitch for turbulent flow was obtained which realizes to make predictions to the friction factor for turbulent flow.
