Similarity analysis for natural convection from a vertical plate with distributed wall concentration

International Journal of Mathematics and Mathematical Sciences, 2000
Steady laminar natural convection flow over a semi-infinite vertical plate is examined in this paper. It is assumed that the concentration of a species along the plate follows some algebraic law with respect to chemical reaction.

Domain-decomposed preconditionings for transport operators [PDF]

The performance was tested of five different interface preconditionings for domain decomposed convection diffusion problems, including a novel one known as the spectral probe, while varying mesh parameters, Reynolds number, ratio of subdomain diffusion ...

Quasi-Linear Convection-Dominated Transport Problem Based on Characteristics-Mixed Finite Element Method

Discrete Dynamics in Nature and Society, 2013
We propose the characteristics-mixed method for approximating the solution to a convection-dominated transport problem. The new method is a combination of characteristic approximation to handle the convection part in time and a mixed finite element ...

An Efficient Numerical Model for the Black–Scholes Equations

Journal of Applied Mathematics
In this paper, a novel numerical model for the Black–Scholes equations is developed. To address some potential issues that may arise when solving this equation using the conventional model, the original Black–Scholes equation is reformulated as a ...

Electro-thermal convection in a Brinkman porous medium saturated by nanofluid

Ain Shams Engineering Journal, 2017
Thermal instability in a horizontal layer of nanofluid with vertical AC electric field in a porous medium is investigated. Brinkman–Darcy model is used for the momentum equation. The model used for nanofluid incorporates the effect of Brownian diffusion,

Continuity Of The Blow-Up Time For A Nonlinear Convection In Reaction-Diffusion Equation

Trends in Computational and Applied Mathematics
In this paper, we consider a nonlinear convection reaction diffusion equation. Under some assumptions, we show that the solution of the problem blows up in a finite time and we estimate its blow-up time.
