节能型无堵塞纸浆泵的关键技术研究与产业化(系列报道之二) 弯曲扩张通道内纤维悬浮流数值模拟

Key technology research and industrialization on energy saving and non-blockage pulp pumps (SeriesⅡ) Numerical simulation of fiber suspension fluid in expanded curve channel

采用Jeffery方程方法,对弯曲扩张通道内悬浮流中纤维初始取向、进口速度、纤维初始位置及长径比rp数对纤维取向的影响作了研究。同时采用Fokker-Planck方程方法,研究通道内的纤维平面取向的稳态分布。

The effect of fiber initial orientation, inlet velocity, fiber＇s original position and the ratio of length to width on the fiber orientation was studied with Jeffery equation. Meanwhile, the stable distribution of plane orientation in the channel was studied with Fokker-Planck equation.
