Bautista-Manero流体在多孔介质中的流动模拟
Modeling the Flow of a Bautista-Manero Fluid in Porous Media
摘要：
在这篇文章中，拉伸流动和粘度和收敛-发散几何检查作为在多孔介质中的特殊粘弹性行为的基础。修正的Bautista-Manero模型，成功地描述了shearnning，弹性和触变的时间依赖性，用于建模的粘弹性材料，也显示触变属性的流动。最初由Philippe Tardy提出的一种算法，采用该模型来模拟稳态时变流，在非牛顿流模拟代码中使用孔隙尺度建模实现，并对初始结果进行了分析。研究结果对未来的进一步发展是令人鼓舞的。
英文摘要：
In this article, the extensional flow and viscosity and the converging-diverging geometry were examined as the basis of the peculiar viscoelastic behavior in porous media. The modified Bautista-Manero model, which successfully describes shearthinning, elasticity and thixotropic time-dependency, was used for modeling the flow of viscoelastic materials which also show thixotropic attributes. An algorithm, originally proposed by Philippe Tardy, that employs this model to simulate steadystate time-dependent flow was implemented in a non-Newtonian flow simulation code using pore-scale modeling and the initial results were analyzed. The findings are encouraging for further future development.
