Iterative Methods for Solving Convection-diffusion Problem

open access: yesComputational 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.

Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films

open access: yesAdvanced Science, EarlyView.
Inverted liquid films, like paint on a ceiling, are inherently unstable under gravity. This work shows that selective evaporation in volatile binary mixtures generates solutal Marangoni stresses that either suppress or amplify the Rayleigh Taylor instability.

Error estimates of characteristic finite elements for bilinear convection–diffusion optimal control problems

open access: yesResults in Applied Mathematics
This paper investigates a fully discrete characteristic finite element approximation of bilinear unsteady convection–diffusion optimal control problems. The characteristic line method is used to treat the convection term and the finite element method is ...

Saturation Assumption and Finite Element Method for a One-Dimensional Model [PDF]

open access: yes, 2002
In this paper we refer to the hierarchical finite element method and stabilization techniques for convection–diffusion equations. In particular, the aim is to outline an application of saturation assumption to a posteriori error estimates for such ...

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...
