| Abstract: | A layer of a compressible couple-stress fluid permeated with suspended particles, heated and soluted from below in a porous medium is considered. For the case of stationary convection, the stable solute gradient and couple-stress have stabilizing effects, whereas the suspended particles and medium permeability have destabilizing effects on the onset or convection in the couple-stress fluid permeated with suspended particles, heated and soluted from below in a porous medium. The effect of compressibility is to postpone the onset of thermosolutal instability. Results are illustrated, graphically, by giving numerical values to the parameters. The system is stable for (cP/g}β > 1; cP, β and g denote specific heat at constant pressure, uniform temperature gradient and acceleration due to gravity, respectively. The stable solute gradient is found to introduce oscillatory modes in the system for (cP/g}β > 1, which were non-existent in its absence. Sufficient conditions for the non -existence of over-stability are also obtained. |
