摘要：
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.
