摘要：
This paper is concerned with the development and study of a stabilized finite volume method for the transient Stokes problem in two and three dimensions. The stabilization is based on two local Gauss integrals and is parameter-free. The analysis is based on a relationship between this new finite volume method and a stabilized finite element method using the lowest equal-order pair (i.e., the P-1 - P-1 pair). 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.
