Journal of Inverse and Ill-Posed Problems, 2018
The inverse coefficient problem for the nonlinear convection-diffusion-reaction equation is considered. A velocity vector and a mass-transfer coefficient are considered as the unknown coefficients and are recovered with the help of the additional ...

The stationary convection-diffusion equation
2009The convection-diffusion equation has been derived in Sect. 1.11. We take ρ = 1, and obtain $$ \frac{\partial\varphi}{\partial t} + u_{\alpha} \varphi,\alpha - (D\varphi,\alpha),\alpha = q, x \in \Omega \subset {\mathbb R}^d, 0 < t \leq T.$$ For the physical significanece of the terms in this equation, see Sect. 1.11.

Supersymmetry and convection–diffusion–reaction equations
International Journal of Modern Physics B, 2023In this work, we are concerned with generating solutions of a class of Convection–Diffusion–Reaction (CDR) equation from the solutions of another CDR equation through the Darboux transformations. The method is elucidated by cases with certain types of the reaction coefficients.

On approximation to convective diffusion equation
Mathematical Methods in the Applied Sciences, 1987AbstractA 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
2009In 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, 2003AbstractHierarchical 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.
