Matrix-equation-based strategies for convection–diffusion equations [PDF]

open access: yesBIT Numerical Mathematics, 2015
We are interested in the numerical solution of nonsymmetric linear systems arising from the discretization of convection-diffusion partial differential equations with separable coefficients and dominant convection. Preconditioners based on the matrix equation formulation of the problem are proposed, which naturally approximate the original discretized ...

A survey of numerical schemes for transportation equation [PDF]

open access: yesE3S Web of Conferences, 2021
The convection-diffusion equation is a fundamental equation that exists widely. The convection-diffusion equation consists of two processes: diffusion and convection. The convection-diffusion equation can also be called drift-diffusion equaintion.
