摘要: A layer of electrically conducting couple-stress fluid heated from below in porous medium presence magnetic field is considered. For stationary convection, the couplestress and postpone onset convection whereas permeability hastens convection. The introduces oscillatory modes system which were non-existent its absence. sufficient condition for non-existence overstability obtained.
