摘　　要：采用Jeffery方程对旋转直扩张通道内的纤维悬浮流进行数值模拟,研究进口速度、旋转速度、纤维初始位置及初始取向对纤维运动的影响,同时,在考虑纤维间相互作用的情况下,通过求解取向概率分布函数,来研究稳态时的纤维取向分布。The numerical simulation of fiber suspension fluid in rotary straightly expanded channel was carried out with Jeffery equation, the effect of inlet velocity, rotating velocity, fiber＇s original position and orientation on the motion of fibers was studied. Meanwhile, considering the interaction between fibers, orientation distribution of fibers in stable conditions were studied by solving the function of orientation probability distribution.
