其他摘要：In the context of the Finite Element Method, the Navier-Stokes equations for incompressible flow are solved using a methodology presented in [1,2]. This technique is the adaptted form of the generalized streamline operator (GSO) presented by Hughes et al. [3J for compressible flows. This new methodology allows the use of equal order interpolation for the unknowns of the problem: velocity and pressure. In this context, the definition of the "upwinding tensor" does not require parameters defined ontside this model. Further, the interface motion problem is taken into account by means of the methodology presented in [4]. Finally, this formulation has been checked in several tests with satisfactory results.
