Assessment of a high-order finite difference upwind scheme for the simulation of convection-diffusion problems
(John Wiley & Sons Ltd, 2009-05-10)
This article deals with the Study of the development and application of the high-order upwind ADBQUICKEST scheme, an adaptative bounded version of the QUICKEST for unsteady problems (Commun. Numer Meth. Engng 2007; ...
Alternate treatments of jacobian singularities in polar coordinates within finite-difference schemes
(World Academic UnionLiverpool, 2012)
Jacobian singularities of differential operators in curvilinear coordinates occur when the Jacobian
determinant of the curvilinear-to-Cartesian mapping vanishes, thus leading to unbounded coefficients in par-tial differential ...
Alternate treatments of jacobian singularities in polar coordinates within finite-difference schemes
(2012-12-27)
Jacobian singularities of differential operators in curvilinear coordinates occur when the Jacobian determinant of the curvilinear-to-Cartesian mapping vanishes, thus leading to unbounded coefficients in partial differential ...

SECOND-ORDER FINITE DIFFERENCE APPROXIMATIONS OF THE UPPER-CONVECTED TIME DERIVATIVE\ast
(Siam Publications, 2021-01-01)
In this work, new finite difference schemes are presented for dealing with the upper convected time derivative in the context of the generalized Lie derivative. The upper-convected time derivative, which is usually encountered ...
A fourth-order compact finite volume scheme for fully nonlinear and weakly dispersive Boussinesq-type equations. Part II: Boundary conditions and validation
(WILEY, 2007)
This paper supplements the validation of the fourth-order compact finite volume Boussinesq-type model presented by Cienfuegos et al. (Int. J. Numer. Meth. Fluids 2006, in press). We discuss several issues related to the ...
