A Multigrid Accelerated High-order Compact Fractional-step Method for Unsteady Incompressible Viscous Flows
The objective of this study is the development of an efficient high-order compact scheme for unsteady incompressible viscous flows. The scheme is constructed on a staggered Cartesian grid system in order to avoid spurious oscillations in the pressure field. Navier-Stokes equations are advanced in time with the second order Adams-Bashford method without considering the pressure terms in the pred...
متن کاملA Finite Element Method for Viscous Incompressible Thermal Flows
A finite element method for steady-state viscous incompressible thermal flows has been developed. The finite element equations are derived from a set of coupled nonlinear Navier-Stokes equations that consists of the conservation of mass, momentum, and energy equations. These derived finite element equations are validated by developing a corresponding finite element computer program that can be ...
متن کاملAn ‘assumed Deviatoric Stress-pressure- Velocity’ Mixed Finite Element Method for Unsteady, Convective, Incompressible Viscous Flow: Part I: Theoretical Development*
A formulation of a mixed finite element method for the analysis of unsteady, convective, incompressible viscous flow is presented in which: (i) the deviatoric-stress, pressure, and velocity are discretized in each element, (ii) the deviatoric stress and pressure are subject to the constraint of the homogeneous momentum balance condition in each element, a priori, (iii) the convective accelerati...
متن کاملA stabilized nonconforming finite element method for incompressible flow
In this paper we extend the recently introduced edge stabilization method to the case of nonconforming finite element approximations of the linearized Navier-Stokes equation. To get stability also in the convective dominated regime we add a term giving L2-control of the jump in the gradient over element boundaries. An a priori error estimate that is uniform in the Reynolds number is proved and ...
متن کاملA finite element variational multiscale method for incompressible flow
In this article, we present a finite element variational multiscale (VMS) method for incompressible flows based on two local Gauss integrations, and compare it with common VMS method which is defined by a low order finite element space Lh on the same grid as Xh for the velocity deformation tensor and a stabilization parameter a. The best algorithmic feature of our method is using two local Gaus...
