on the onset of triple-diffusive convection in a horizontal layer of nanofluid heated from below and salted from above and below is studied both analytically and numerically. the effects of thermophoresis and brownian diffusion parameters are also introduced through buongiorno model in the governing equations. by using linear stability analysis based on perturbation theory and applying normal m...

We study the local stability of stratified, differentially-rotating fluids to axisymmetric perturbations in the presence of a weak magnetic field and of finite resistivity, viscosity and heat conductivity. This is a generalization of the Goldreich-Schubert-Fricke (GSF) double-diffusive analysis to the magnetized and resistive, triple-diffusive case. Our fifth-order dispersion relation admits a ...

Solid-solid transitions between crystals follow diffusive nucleation, or various diffusionless transitions, but these kinetics are difficult to predict and observe. Here we observed the rich kinetics of transitions from square lattices to triangular lattices in tunable colloidal thin films with single-particle dynamics by video microscopy. Applying a small pressure gradient in defect-free regio...

Abstract Diffusive transport in porous media is a complex process multi-scaled fractured modeling. This paper presents diffusive model for non-Dacian flow naturally reservoir with triple porosity and permeability. To address the non-Darcian behavior associated fluid media, Darcy/Forcheimer equation was used. A point-diffusive obtained from mass conservation Darcy–Forcheimer momentum equation; t...

One of the practical methods for examining stability and dynamical behaviour non-linear systems is weakly analysis. Time-varying gravitational acceleration triple-diffusive convection play a significant role in formation acceleration, inducing some dynamics industry. With an emphasis on natural Rayleigh–Bernard convection, more needed significance modulated field heat mass transfer due to tripl...
