Abstract

SMOKES VORTICES CONVECTION VORTEX FLOW ANNULAR SPACE LAMINAR FLOW DISTORTION BUOYANCY SYMMETRY CYLINDERS FLOW VISUALIZATION GAS INJECTION RAYLEIGH−TAYLOR INSTABILITY
A flow visualization study, using smoke injected into the annular gap between concentric vertical cylinders, has been completed to determine the effects of buoyancy on the development and structure of Taylor vortices. The experimental facility consists of a heated, rotating inner cylinder enclosed by a transparent, stationary outer cylinder. Stationary horizontal endplates are used to seal the annulus. The axisymmetric Taylor vortex flow becomes distorted as buoyancy is introduced into the system. With increasing buoyancy, the flow undergoes a transition to a spiral form, after which another axisymmetric cellular pattern emerges. Finally, the natural convection flow pattern is established.
