In this paper, we consider a non-Newtonian fluid and electrorheological fluid mixed-type equation vt=div(b(x)|v|α(x)|v|p2v)+f(x,t,v),where p>1, b(x)0 and α(x)0. The existence of weak solution is investigated by means of the parabolically regularized method. Due to |v|L(0,T;Llocp(Ω)), the stability of weak solution is established by choosing a suitable test function and the local stability is also discussed without any boundary value condition.

非牛顿流体与电流变流体混合型方程的稳定性

在本文中,我们考虑了一个非牛顿流体和电流变流体混合型方程v=div(b(X)|v|α(X)|v|p-2v)+F(X,,v),其中p > 1,b(X)0α(X)0. 采用抛物正则化方法研究弱解的存在性。由于|v|大号(0,;大号lCp(Ω)),通过选择合适的测试函数来建立弱解的稳定性,并且在没有任何边界值条件的情况下也讨论了局部稳定性。
