The effect of the Suction-Injection-Combination (SIC) on the onset of Rayleigh-Benard convection in suspensions is studied in a porous medium using the Rayleigh-Ritz technique. The critical eigenvalue is obtained for free-free, free-rigid and rigid-rigid boundary combinations with isothermal or adiabatic temperature condition. The microrotation of the suspended particles is assumed to vanish at the boundaries. The effect of the SIC on the critical eigenvalue is shown to be dependent on whether it is gravity-aligned or anti-gravity. The classical results on the effect of suspended particles on convection is found to be unaltered by the SIC. The problem has industrial applications.
