Three-dimensional flow with Cattaneo–Christov double diffusion and homogeneous-heterogeneous reactions

Results in Physics, 2017
Here three dimensional (3D) flow of second grade fluid has been studied in the presence of Cattaneo–Christov double diffusion and heterogeneous-homogeneous reactions. Flow is bounded by a bidirectional linear stretchable surface.

Impact of Moving Walls and Entropy Generation on Doubly Diffusive Mixed Convection of Casson Fluid in Two-Sided Driven Enclosure

Entropy
In this study, numerical simulations are conducted with the goal of exploring the impact of the direction of the moving wall, solute and thermal transport, and entropy production on doubly diffusive convection in a chamber occupied by a Casson liquid ...

Generalized theory of thermoelastic diffusion with double porosity

Archives of Mechanics, 2018
The present paper focuses on the derivation of the constitutive relations and field equations for anisotropic thermoelastic medium with mass diffusion and double porosity. The variational principle, uniqueness and reciprocity theorems are also derived.

Double-Jump migration and diffusive instability [PDF]

Bulletin of Mathematical Biology, 2004
In order to look into the stability consequences of a particular migration process in which individuals choose to settle, we formulated a continuous-time multi-species multi-patch model in which individuals migrate by one or two instantaneous jumps while making the second jump with a certain probability that possibly depends on the conditions at the ...

Geometrical Optics Stability Analysis of Rotating Visco-Diffusive Flows

Mathematics
Geometrical optics stability analysis has proven effective in deriving analytical instability criteria for 3D flows in ideal hydrodynamics and magnetohydrodynamics, encompassing both compressible and incompressible fluids. The method models perturbations

Modelling double diffusion in soils and materials

Journal of the Mechanical Behavior of Materials, 2018
The double diffusivity model proposed earlier by Aifantis and co-workers was applied in this work for modelling the diffusion of metals in sandy aquifers, as well as chloride diffusion in concrete specimens.

Twisted and Nontwisted Bifurcations Induced by Diffusion

, 1996
We discuss a diffusively perturbed predator-prey system. Freedman and Wolkowicz showed that the corresponding ODE can have a periodic solution that bifurcates from a homoclinic loop.

Bi-directional stretched nanofluid flow with Cattaneo-Christov double diffusion

Results in Physics, 2019
Bi-directional unsteady flow of nanomaterial has been explored in the existence of Cattaneo-Christov double diffusion. Brownian motion, thermophoresis and heat sources namely PST (prescribed surface temperature) and PHF (prescribed heat flux) are ...
