چکیده

In this work, the linear and weakly nonlinear stability inspections on thermal convection of hybrid nanomaterial in a porous medium are made using modified Buongiorno two-phase Darcy model. Analytical expression for critical nanofluid dimensionless number onset convective motion is obtained theory. current situation investigation, transient heat transport arrangement form Nu numerically R-K45 procedure. The numerical results offered water–copper–silver nanofluid. indicate that boost value volume concentration nanoparticle parameters to rapid layers. increases at most 21.9% with an augment 3% estimate \(R_{{{\text{hnf}}}}\) 2% fraction nanoparticles.

Flow field and heat transfer of MgO-Ag/water micropolar hybrid nanofluid in a permeable channel

In this study, the least square method is applied to study the laminar flow, heat transfer and microrotation of MgO-Ag/water micropolar hybrid nanofluid in a permeable channel. The bottom wall is hot and coolant fluid is injected into the channel from the top wall. The base fluid in the channel is water and volume fraction of nanoparticle (50% Ag and 50% MgO by volume) is between 0 and 0.02. By...

Convective instability of strained layer step-flow

We examine an epitaxial crystal growth model in the context of absolute and convective instabilities and show that a strain-induced step bunching instability can be convective. Using analytic stability theory and numerical simulations, we study the response of the crystal surface to an inhomogeneous deposition flux that launches impulsive and time-periodic perturbations to a uniform array of st...
