Existence of Weak Solutions for a Diffuse Interface Model of Non-Newtonian Two-Phase Flows

Helmut Abels, Lars Diening, Yutaka Terasawa

摘要:

本文考虑两种部分互溶不可压缩粘性非牛顿(幂律)流体流动的相场模型。在该模型中,假设流体的密度相等。我们证明了弱解的存在性一般的初始数据和任意大的时间与援助的抛物Lipschitz截断方法,保持螺线管速度场,最近开发的Breit,Diening,和Schwarzacher。

英文摘要:

We consider a phase field model for the flow of two partly miscible incompressible, viscous fluids of Non-Newtonian (power law) type. In the model it is assumed that the densities of the fluids are equal. We prove existence of weak solutions for general initial data and arbitrarily large times with the aid of a parabolic Lipschitz truncation method, which preserves solenoidal velocity fields and was recently developed by Breit, Diening, and Schwarzacher.
