一类非牛顿流体两相自由边界问题的强解

Strong solutions for two-phase free boundary problems for a class of non-Newtonian fluids

Matthias Hieber, Hirokazu Saito

摘要:

考虑一类非牛顿流体在表面张力和重力作用下的两相自由边界问题,其应力张量$T_i$对于$i=1,2$分别为$T_i=-πI+μ_i(|D(v)|^2)D(v)$,其中粘度函数$μ_i$满足$μ_i(s)\in C^3([0,\infty))$和$μ_i(0)>0$对于$i=1,2$ .它表明,对于给定的$T>0$这个问题承认一个独特的,强的解决方案,$(0,T)$提供的初始数据是足够小的自然规范。

英文摘要:

Consider the two-phase free boundary problem subject to surface tension and gravitational forces for a class of non-Newtonian fluids with stress tensors $T_i$ of the form $T_i=-πI+μ_i(|D(v)|^2)D(v)$ for $i=1,2$, respectively, and where the viscosity functions $μ_i$ satisfy $μ_i(s)\in C^3([0,\infty))$ and $μ_i(0)>0$ for $i=1,2$. It is shown that for given $T>0$ this problem admits a unique, strong solution on $(0,T)$ provided the initial data are sufficiently small in their natural norms.
