Mathematical modelling of free convection in a square cavity filled with a bidisperse porous medium for large values of Rayleigh number [PDF]
A free convection problem for bidisperse porous media is considered. The numerical solutions are obtained using an algorithm based on an nonuniform grid.

Aerodynamic Characteristics of Joukowsky Like Wings [PDF]
Aerodynamic characteristics of Joukowsky like airfoils are analyzed, under the assumption that the flow near the airfoil is governed by two-dimensional incompressible isothermal Newtonian fluid flow, beyond the viscous boundarylayer of which is ...

A Note On Immersed Interface Method For Three Dimensional Elliptic Equations [PDF]
. The Immersed Interface Method proposed by LeVeque and Li [SIAM J. Numer. Anal. 31, No.4 (1994)] is extended to three dimensional elliptic equations of the form: r \Delta (fi(x)ru(x)) + (x)u(x) = f(x): We study the situation in which there is an ...

A Cost-Effective Multigrid Projection Operator [PDF]
A novel heuristic residual analysis is proposed to derive a computationally cost-effective residual projection operator in multigrid with the five-point Red-Black Gauss-Seidel relaxation for solving the two dimensional Poisson equation.

Shift, Symmetry, and Asymmetry in Polynomial Sequences.
In this study, we show the existence of three types of shifts in polynomial curves in the XY-plane that will always result in integer sequences: 1. "Eureka shift”, 2. Taylor shift, and 3. “Taylor shift and fit”.

Discrete Models of Time-Fractional Diffusion in a Potential Well [PDF]
Mathematics Subject Classification: 26A33, 45K05, 60J60, 60G50, 65N06, 80-99.By generalization of Ehrenfest’s urn model, we obtain discrete approximations to spatially one-dimensional time-fractional diffusion processes with drift towards the origin ...
