ABSTRACT:
Condition for characterizing nonoscillatory motions, which may be neutral or unstable, for rotatory hydrodynamic triply diffusive convection in a porous medium is derived. It is analytically proved that the principle of the exchange of stabilities, in rotatory triply diffusive convection in a porous medium, is valid in the regime (R_1 E_1 s)/(2t_1^2 p^4 )+(R_2 E_2 s)/(2t_2^2 p^4 )+ T_a/(p^2 ?D_a^(-1) )=1, where R_1 and R_2 are the concentration Raleigh numbers, and t_1 and t_2 are the Lewis numbers for the two concentration components respectively, T_a is the Taylor number, s is the Prandtl number, D_a is the Darcy number, E_1 and E_2 are constants.
