Onset of Double Diffusive Convection in a Thermally Modulated Fluid-Saturated Porous Medium

d Academy of Romanian Scientists, 050094 Bucuresti, Romania Reprint requests to Cor. They satisfy all imposed initial and boundary conditions and can generate a large class of

To obtain these stability curves, we fix the value of Ω first and then calculate the value of the critical Rayleigh number R ac and the correspond- ing value of the wave number a c

Thus σ i = 0, which means that oscillatory modes are not allowed and the principle of exchange of stabilities is satisfied for a porous medium in com- pressible, couple-stress fluid

[13] have considered the thermal instability of a layer of a couple-stress fluid acted on by a uniform rotation, and have found that for stationary convection, the rotation has
