چکیده

In this paper, we are interested in the mathematical analysis of a non-classical conservation law. The model describes stratigraphic processes of the geology, taking into account a limited weathering condition. Firstly, we present the physical topic and the mathematical formulation, which lead to an original conservation law. Then, the definition of a solution and some mathematical tools in order to prove the existence of a solution. Un resultado de existencia para una ecuación original de difusión-convección Resumen. En este artı́culo se estudia el análisis matemático de una ley de conservación que no es clásica. El modelo describe procesos estatigráficos en Geologı́a y tiene en cuenta una condición de tasa de erosión limitada. En primer lugar se presentan el modelo fı́sico y la formulación matemática (posiblemente nueva). Tras enunciar la definición de solución, se presentan las herramientas que permiten probar la existencia de soluciones.

Finite integration method with RBFs for solving time-fractional convection-diffusion equation with variable coefficients

In this paper, a modification of finite integration method (FIM) is combined with the radial basis function (RBF) method to solve a time-fractional convection-diffusion equation with variable coefficients. The FIM transforms partial differential equations into integral equations and this creates some constants of integration. Unlike the usual FIM, the proposed method computes constants of integ...

Finite Element Methods for Convection Diffusion Equation

This paper deals with the finite element solution of the convection diffusion equation in one and two dimensions. Two main techniques are adopted and compared. The first one includes Petrov-Galerkin based on Lagrangian tensor product elements in conjunction with streamlined upwinding. The second approach represents Bubnov/Petrov-Galerkin schemes based on a new group of exponential elements. It ...

Degenerate Convection-Diffusion Equation with a Robin boundary condition

We study a Robin boundary problem for degenerate parabolic equation. We suggest a notion of entropy solution and propose a result of existence and uniqueness. Numerical simulations illustrate some aspects of solution behaviour. Monodimensional experiments are presented. Mathematics Subject Classification (2010). Primary 35F31; Secondary 00A69.

Thermosolutal Convection of Micropolar Rotating Fluids Saturating a Porous Medium

Double-diffusive convection in a micropolar fluid layer heated and soluted from below in the presence of uniform rotation saturating a porous medium is theoretically investigated. An exact solution is obtained for a flat fluid layer contained between two free boundaries. To study the onset of convection, a linear stability analysis theory and normal mode analysis method have been used. For the ...
