Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.

计算流变学在聚合物加工、粘附和理解极高剪切速率下的润滑等问题中的成功实际应用，需要对流体的充分描述（本构方程）和适当边界条件的规定。本构模型问题已得到广泛研究，本提案旨在解决流动流体和固体表面之间界面处粘弹性流动的适当边界条件问题。 这一重要领域尚未在理论上和计算上得到彻底研究，我们试图通过分子动力学来阐明其机制。
