摘要：

The thermal instability of micropolar fluids heated from below in the presence of uniform rotation in porous medium has been considered. It is found that the presence of coupling between thermal and micropolar effects, uniform rotation and permeability may introduce oscillatory motions in the system. The increase in Rayleigh number for the stationary convection and decrease in Rayleigh number for overstability with the increase in permeability is depicted graphically. Also the Rayleigh number is found to increase with the increase in rotation.
