摘要
本文回顾了纤维悬浮液模拟的方法 ,并对模拟的方法进行了简单的探讨 ,主要包括Ewald求和模拟技术 ,使用摩擦力考虑了短范围的作用力和微小体近似来考虑长范围作用力 ,还有BCF和适合粘性分离应力 (AVSS)的有限元公式的结合。
The numerical methods to simulate fibre suspensions in shear flow are reviewed, the methods of simulation are simply disscussed,which takes into account short range interaction via lubrication forces and long range interaction via slender body approximation,together with an appropriate Ewald summation technique.Another method is a combination of the Brownian configuration field(BCF) technique and the adaptive viscosity split stress(AVSS) finite element formulation.The numerical results are averaged to evalulate macroscopic properties of the suspension.
