Analytical and numerical stability analysis of Soret-driven convection in a horizontal porous layer [PDF]
, 2007 We present an analytical and numerical stability analysis of Soret-driven convection in a porous cavity saturated by a binary fluid. Both the mechanical equilibrium solution and the monocellular flow obtained for particular ranges of the physical ...

On Algebraically Stabilized Schemes for Convection–Diffusion–Reaction Problems
, 2022 An abstract framework is developed that enables the analysis of algebraically stabilized discretizations in a unified way. This framework is applied to a discretization of this kind for convection–diffusion–reaction equations.

Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Supersymmetry and convection–diffusion–reaction equations
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.

Travelling wave for absorption-convection-diffusion equations
Electronic Journal of Differential Equations, 2006 In this paper, we use the phase plane method for finding finite travelling waves solutions for the diffusion-absorption-convection equation $$ u_t=A(|u_x|^{p-2}u_{x})_x+B(u^n)_x-Cu^q, quad (x,t)in mathbb{R}imes mathbb{R}^{+}.
