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 ...

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.

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.

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.

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.

Approximate Convection-Diffusion Equations

Journal of Hydrologic Engineering, 1999
This paper describes the development of simplified momentum equations, in stage as well as in discharge formulations, governing the transition between the diffusion and the kinematic waves (including the latter). It also describes the application of these equations to arrive at the approximate convection-diffusion equations.
