Abstract : The stability of a viscous flow between two concentric rotating porous cylinders has been examined when the difference in radii of the cylinders is small in comparison with their mean radius. Critical Taylor numbers have been calculated for various wave numbers and velocity ratios of the cylinders. Theroetical results show that injection at the outer cylinder improves the stability of the flow whereas suction has an opposite effect.
