It was found that at two different values of the Prandtl number considered the instability is caused by different infinitely small dominant perturbations, which means that the convective heat transfer strongly affects stability of the flow even for cases having small Prandtl number. Abstract: The manuscript reports the stability mechanism of chemically reacting Double diffusive free convective flow in a horizontal layer of viscoelastic Maxwell fluid through porous medium with internal linear heating. The flow is also induced by the magnetic effect which gravitational aligned (0,0,-g). Due to.

A problem of stability of steady convective flows in rectangular cavities is revisited and studied by a second‐order finite volume method. The study is motivated by further applications of the finite volume‐based stability solver to more complicated applied problems, which needs an estimate of convergence of critical parameters. It is shown that for low‐order methods the quantitatively.

The existence of a characteristic scale close to wavelengths, as that of JEANS, is revealed. In this paper bifurcation theory and group theoretical methods are applied to the analysis of the stationary convection of a fluid filling a spherical shell which is rotating (or not rotating) about an axis with a constant angular speed.

In the case with rotation, an analytical relation is found between the Rayleigh number and the Taylor number, for which a transcritical branch of stationary. A universal criterion for the stability under arbitrary disturbances of the convective flow of a fluid in a porous medium is obtained in terms of a Reynolds number and a Rayleigh number for the flow.

It is also shown that stability bounds obtained by small perturbation methods are equally good bounds under arbitrary disturbances.In meteorology, convective instability or stability of an air mass refers to its ability to resist vertical motion.

A stable atmosphere makes vertical movement difficult, and small vertical disturbances dampen out and disappear. In an unstable atmosphere, vertical air movements (such as in orographic lifting, where an air mass is displaced upwards as it is blown by wind up the rising slope of.The linear stability of thermally stratified horizontal two‐phase Couette flow is analyzed for the case of a constant vertical temperature gradient.
