Iterative Methods for Solving Convection-diffusion Problem
Computational Methods in Applied Mathematics, 2002 AbstractTo obtain an approximate solution of the steady-state convectiondiffusion problem, it is necessary to solve the corresponding system of linear algebraic equations. The basic peculiarity of these LA systems is connected with the fact that they have non-symmetric matrices.

Heat transfer analysis for a free boundary problem arising in n-diffusion equation
Propulsion and Power Research, 2016 This paper presents research on a free boundary value problem arising in a nonlinear n-diffusion equation by using a homotopy analysis method (HAM). Approximate analytical solutions are obtained for special nonlinear diffusion functional coefficient ...

An Adaptive Multigrid Strategy for Convection-Diffusion Problems [PDF]
, 2006 *Abstract. *For the solution of convection-diffusion problems we presenta multilevel self-adaptive mesh-refinement algorithm to resolve locallystrong varying behavior, like boundary and interior layers. The methodis based on discontinuous Galerkin (Baumann-Oden DG) discretization.The recursive mesh-adaptation is interwoven with the multigrid solver.The

An inverse problem for a quasilinear convection–diffusion equation
Nonlinear Analysis, 2022 We study the inverse problem of recovering a semilinear diffusion term $a(t,λ)$ as well as a quasilinear convection term $\mathcal B(t,x,λ,ξ)$ in a nonlinear parabolic equation $$\partial_tu-\textrm{div}(a(t,u) \nabla u)+\mathcal B(t,x,u,\nabla u)\cdot\nabla u=0, \quad \mbox{in}\ (0,T)\timesΩ,$$ given the knowledge of the flux of the moving quantity ...

Uniform convergence on a Bakhvalov-type mesh using the preconditioning approach: Technical report [PDF]
, 2015 The linear singularly perturbed convection-diffusion problem in one dimension is considered and its discretization on a Bakhvalov-type mesh is analyzed. The preconditioning technique is used to obtain the pointwise convergence uniform in the perturbation
