Numerical Solutions for Convection-Diffusion Equation through Non-Polynomial Spline
MATEC Web of Conferences, 2016 In this paper, numerical solutions for convection-diffusion equation via non-polynomial splines are studied. We purpose an implicit method based on non-polynomial spline functions for solving the convection-diffusion equation.

The Astrophysical Journal, 2023 We investigate heat transport associated with compositionally driven convection driven by crystallization at the ocean–crust interface in accreting neutron stars, or growth of the solid core in cooling white dwarfs.

Anisotropic Diffusion in Driven Convection Arrays
Entropy, 2021 We numerically investigate the transport of a Brownian colloidal particle in a square array of planar counter-rotating convection rolls at high Péclet numbers. We show that an external force produces huge excess peaks of the particle’s diffusion constant

On the Generalized Fractional Convection–Diffusion Equation with an Initial Condition in
Fractal and FractionalTime-fractional convection–diffusion equations are significant for their ability to model complex transport phenomena that deviate from classical behavior, with numerous applications in anomalous diffusion, memory effects, and nonlocality.

A convection-diffusion elliptic system
Rendiconti di Matematica e delle Sue Applicazioni, 2009 We study a convection-diffusion elliptic system, with Dirichlet boundary conditions. In some cases, we will prove that we have more informations (with respect to the case of a single equation) about the summability of the solutions and of their gradients, thanks to the structure of our system.

Convective Diffusion of an Enzyme Reaction [PDF]
SIAM Journal on Applied Mathematics, 1977 The evolution of a simple enzyme reaction being convected by Poiseuille flow in a semi-infinite tube is considered. When the effects of diffusion are ignored, the solutions for the concentrations of enzyme and substrate are analogues of the spatially independent case. When small but nonzero diffusion coefficients are admitted the solutions are modified

Some Inverse Problems for Convection-Diffusion Equations
Bulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2014 We examine the well-posedness questions for some inverse problems in the mathematical models of heat-and-mass transfer and convection-di usion processes. The coe cients and right-hand side of the system are recovered under certain additional overdetermination conditions, which are the integrals of a solution with weights over some collection of domains.
