摘要
In this paper, a Galerkin /least squares-type finite element method is proposed for a quasi-Newtonian flow, where the viscosity obeys the power law, The method is consistent and stable for P1/P1(PO) and Q1/Q1(QO) combination of discrete velocity and pressure spaces (without requiring the "inf-sup" stability condition).The existence, uniqueness and convergence of the discrete solution is proved.
