ABSTRACT:
The paper mathematically establishes that the complex growth rate (p_(r ),p_i) of an arbitrary neutral or unstable oscillatory perturbation of growing amplitude, in a triply diffusive fluid layer in porous medium (Darcy Model) with one of the components as heat with diffusivity ?, must lie inside a semicircle in the right- half of the (p_(r ),p_i)-plane whose centre is origin and radius equals v((R_1+R_2)s), where R_1 and R_2 are the Raleigh numbers for the two concentration components with diffusivities ?_1 and ?_2 (with no loss of generality, ?>?_1>?_2 ) and s is the Prandtl number. Further, it is proved that above result is uniformly valid for quite general nature of the bounding surfaces.
