Finite element approximation and preconditioning for anisothermal flow of implicitly-constituted non-Newtonian fluids

We devise 3-field and 4-field finite element approximations of a system describing the steady state of an incompressible heat-conducting fluid with implicit non-Newtonian rheology. We prove that the sequence of numerical approximations converges to a weak solution of the problem. We develop a block...
