Pore-scale evaluation of CO2 miscible displacement in porous rocks induced by convection and diffusion: implications for CO2 geo-sequestration

International Journal of Coal Science & Technology
CO2 enhanced oil recovery plays an important role in carbon storage and utilization. However, the incomplete understanding of the underlying microscopic convection–diffusion mechanisms in complex pore structures has constrained the broader industrial ...

The diffusive regime of double-diffusive convection [PDF]

Progress in Oceanography, 2003
The diffusive regime of double-diffusive convection is discussed, with a particular focus on unresolved issues that are holding up the development of large-scale parameterizations. Some of these issues, such as interfacial transports and layer-interface interactions, may be studied in isolation. Laboratory work should help with these.

Diffusion-free Dynamics in Rotating Spherical Shell Convection Driven by Internal Heating and Cooling

The Astrophysical Journal
The bulk properties of convection in stellar and giant planet interiors are often assumed to be independent of the molecular diffusivities, which are very small.

Fujita type theorem for a class of coupled quasilinear convection–diffusion equations

Boundary Value Problems, 2021
In this paper, we establish the Fujita type theorem for a homogeneous Neumann outer problem of the coupled quasilinear convection–diffusion equations and formulate the critical Fujita exponent. Besides, the influence of diffusion term, reaction term, and

On the Generalized Fractional Convection–Diffusion Equation with an Initial Condition in ${\mathbb{R}}^{\mathit{n}}$

Fractal and Fractional
Time-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 Weighted Average Finite Difference Method for the Fractional Convection-Diffusion Equation

Advances in Mathematical Physics, 2013
A weighted average finite difference method for solving the two-sided space-fractional convection-diffusion equation is given, which is an extension of the weighted average method for ordinary convection-diffusion equations.
