Velocity–vorticity formulation for 3D natural convection in an inclined cavity by DQ method

International Journal of Heat and Mass Transfer, 2007
Abstract The present work proposes a novel numerical solution algorithm based on a differential quadrature (DQ) method to simulate natural convection in an inclined cubic cavity using velocity–vorticity form of the Navier–Stokes equations. Since the DQ method employs a higher-order polynomial to approximate any given differential operator, the ...

L.E.S. of a spatially developing 3D incompressible mixing layer with velocity vorticity formulation

Lecture Notes in Physics, 1998
The spatial development of a 3D plane mixing layer in incompressible flow has been performed using a L.E.S. approach. The resolutions of the Navier-Stokes equations, written in velocity-vorticity formulation, is based on an original fractional step algorithm (Bertagnolio et al. (1996)).

Vorticity-Velocity formulation for the stationary Navier-Stokes equations: The three-dimensional case

Applied Mathematics Letters, 1995
In this article, we propose a mixed method for the vorticity-velocity formulation of the stationary Stokes and Navier-Stokes equations in space dimension three, the unknowns being the vorticity and the velocity of the ...

On the velocity-vorticity formulation of the stokes system in two and three-dimension spaces

Mechanics Research Communications, 1995
The paper treats the velocity-vorticity version of the stationary Stokes equations for viscous incompressible fluid in a bounded domain. The equivalence of the original system and the velocity-vorticity formulation is proved in both two- and three-dimensional spaces. The equivalence with the variational form is demonstrated, too.

A Spectral Solver for the Navier–Stokes Equations in the Velocity–Vorticity Formulation for Flows with Two Nonperiodic Directions

Journal of Computational Physics, 1997
A novel pseudospectral scheme for the Navier-Stokes equations with two nonperiodic directions is proposed. An influence matrix technique is employed to elicit the a priori lacking boundary conditions for the vorticity. The spatial discretization is based on a two-dimensional Chebyshev expansion on a nonstaggered grid of collocation points.
