Equazioni alle Derivate Parziali nella Dinamica dei Fluidi

# On the existence of classical solution to the steady flows of generalized Newtonian fluid with concentration dependent power-law index

speaker: Anna Abbatiello (Università della Campania "L. Vanvitelli")

abstract: Steady flows of an incompressible synovial 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. It makes the problem much more difficult than the standard model for power-law fluid in the analysis of the system of PDEs, since the variable exponent space $W{1,p(x)}$ is a priori unknown. We investigate the question of the existence of a classical solution for the two dimensional periodic case. \noindent

This is a joint work with M. Bul\'{i}\v{c}ek and P. Kaplick\'y.
