Abstract

Steady flows of an incompressible homogeneous chemically reacting fluid are described by a coupled system, consisting of the generalized Navier-Stokes equations and convection-diffusion equation with diffusivity dependent on the concentration and the shear rate. Cauchy stress behaves like power-law fluid with the exponent depending on the concentration.

We prove the existence of a classical solution for the two dimensional periodic case whenever the power law exponent is above one and less than infinity.
