Abstract:This paper presents a parallel implementation of fractional solvers for the incompressible Navier–Stokes equations using an algebraic approach. Under this framework, predictor–corrector and incremental projection schemes are seen as sub-classes of the same class, making apparent its differences and similarities. An additional advantage of this approach is to set a common basis for a parallelization strategy, which can be extended to other split techniques or to compressible flows.
Keywords:Navier&ndash  Stokes equations   Fractional methods   Stabilized finite element   Predictor&ndash  corrector scheme   Incremental projection scheme   Parallel implementation   High performance computing
