Abstract: | Stability of the flow of a viscous incompressible fluid in a narrow gap between two concentric cylinders rotating in opposite directions is studied. Exact values of critical Taylor number for the first and second modes are derived by a numerical procedure and these are compared with the known results. It is observed that the value of the critical Taylor number Tcrit decreases with increasing the values of a parameter , and the rate of decrease in the value of Tcrit is more when the two cylinders rotate in the opposite directions. |
