| Abstract: | In this paper we develop and study a new stabilized finite volume method for the two-dimensional Stokes equations. This method is based on a local Gauss integration technique and the conforming elements of the lowest-equal order pair (i.e., the P 1–P 1 pair). After a relationship between this method and a stabilized finite element method is established, an error estimate of optimal order in the H 1-norm for velocity and an estimate in the L 2-norm for pressure are obtained. An optimal error estimate in the L 2-norm for the velocity is derived under an additional assumption on the body force. This work is supported in part by the NSF of China 10701001 and by the US National Science Foundation grant DMS-0609995 and CMG Chair Funds in Reservoir Simulation. |
