对于稀相聚合物溶液(Fene哑铃)最简单的非线性动力学理论，用于推导宏观本构方程(Fene-P)的预平均Peterlin近似对模型的统计和流变性质有显著影响。这一点在用标准和随机数值技术对瞬时拉伸流的模拟中得到了说明。©1997 Elsevier Science B.V.保留所有权利。
For the simplest non-linear kinetic theory of dilute polymeric solutions (FENE dumbbells), the pre-averaging Peterlin approximation used to derive a macroscopic constitutive equation (FENE-P) is shown to have a significant impact on the statistical and rheological properties of the model. This is illustrated in simulations of transient elongational flows by means of standard and stochastic numerical techniques. © 1997 Elsevier Science B.V. All rights reserved.
