Results on a Navier-Stokes system with applications to electrorheological fluid flow

Dreyfuss, Pierre ; Hungerbühler, Norbert

In: International Journal of Pure and Applied Mathematics, 2004, vol. 14, p. 241-267

We study a Navier-Stokes system which is motivated by models for electrorheological fluids. Its principal features are the weak monotonicity assumptions we impose on the viscosity tensor. Moreover we allow the viscosity to depend on the velocity in order to cover some of the models in electrorheological theory. We establish existence of a weak solution of the corresponding Navier-Stokes system. Plus
