Estimateurs a posteriori d’erreur pour le calcul adaptatif d’écoulements quasi-Newtoniens. (A posteriori error estimators for adaptive calculation of quasi-Newtonian flows). (French) Zbl 0712.76068

RAIRO, Modélisation Math. Anal. Numér. 25, No. 1, 31-47 (1991).
Summary: We study a posteriori error estimators for the mixed finite element approximation of some quasi-Newtonian flows (fluids whose viscosity varies with the second invariant of the rate of deformation tensor). These estimators necessitate only the evaluation of the local residual of the finite element solution. They can be used in a self-adaptive mesh- refinement process.
