On approximation to convective diffusion equation

Mathematical Methods in the Applied Sciences, 1987
AbstractA closed‐form analytical solution for the problem of homogeneous and heterogeneous reactions in a isothermal non‐Newtonian laminar flow tubular reactor is presented. A technique is evolved where Galerkin method is applied in Laplace‐transformed domain.

Linear Reaction-Convection-Diffusion Equation

2009
In this chapter, we discuss the control problem of the linear reaction-convectiondiffusion equation $$\frac{\partial u}{\partial t} = \mu \nabla^{2} u + \nabla \cdot (u\mathbf{v}) + au.$$ (4.1) Depending on a particular real problem, u can represent a temperature or the concentration of a chemical species.

ℋ︁‐matrices for the convection‐diffusion equation

PAMM, 2003
AbstractHierarchical matrices (ℋ︁‐matrices) provide a technique for the sparse approximation of large, fully populated matrices. This technique has been shown to be applicable to stiffness matrices arising in boundary element method applications where the kernel function displays certain smoothness properties.
