Subject : 532.542 Fluid Dynamics
Keywords : Cylinder ;Velocity ratios;Critical Taylor numbers
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. |

Subject : 536 Thermodynamics
Keywords : Cylinder;Well stirred fluid
Abstract : The transient temperature distribution in a finite hollow cylinder in contact with a well stirred fluid at its outr surface has been obtained. At the inner cylindrical surface cylinder has ben assumed to absorb flux which is sinusoidal along the length of the cylinder and the plane ends of the cylinder have been assumed to be impervious to heat. Some numerical results have been exhibited graphically |
