Particle approximation of convection–diffusion equations

Mathematics and Computers in Simulation, 2001
A particle method is derived for convection-diffusion equations and a convergence theorem is proved. Numerical results are discussed for different quasi random walks. An effective method is determined for replacing pseudo-random sequences in particle simulations with quasi-random sequences.

Incremental unknowns for convection–diffusion equations

Applied Numerical Mathematics, 1993
The authors employ the method of incremental unknowns as suggested by the second author [SIAM J. Math. Anal. 21, No. 1, 154-178 (1990; Zbl 0715.35039)] to improve the convergence rate for some iterative methods applied to finite difference schemes for convection-diffusion equations.

The convection–diffusion equation

2014
AbstractThis chapter concerns the statement of the steady convection–diffusion equation and its weak formulation. This is followed by a description of finite element discretization and properties of the discrete problem, including error bounds, stabilization methods and matrix properties.

An HDG Method for Convection Diffusion Equation

Journal of Scientific Computing, 2015
A new hybridizable discontinuous Galerkin (HDG) method for the convection-diffusion problem on general polyhedral meshes is presented. This new HDG method is a generalization of HDG methods for linear elasticity introduced in [\textit{W. Qiu} et al., ``An HDG method for linear elasticity with strong symmetric stresses'', \url{arXiv:1312.1407}] to ...

The stationary convection-diffusion equation

2009
The 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, 2023
In 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.
