This approach was used to simulate plane Couette flows of dilute polymeric fluids by the FENE dumbbell mode.
采用确定性方法数值求解了聚合物稀溶液的微观-宏观模型,其中,宏观尺度上用有限体积法求解守恒方程,介观尺度上用谱方法求解Fokker-Planck方程和聚合物对偏应力张量的贡献,模拟了聚合物稀溶液FENE哑铃模型的平板Couette流动,给出了速度随时间变化的剖面图,分析了移动平板速度、哑铃的量纲1有限拉伸参数和Deborah数对流动的影响,同时也验证了有限体积法与谱方法结合求解聚合物微观-宏观模型的有效性。
It is proved by the test that the failure of dumbbell shaped specimen in strong-stress-axis direction can be realized by welding corrugated steel webs in its weak-stress-axis direction to increase flexible rigidity in this direct.
