Abstract

The main mechanisms of transition of buoyancy-induced flows in the horizontal annulus betweencircular cylinders are reviewed, based on the available literature. Both experimental and theoreticalstudies are considered. The different scenarios for the evolution of the flow regimes and temperaturepatterns are tracked, for increasing values of the Rayleigh number, Ra. The occurrence of variousinstability and bifurcative phenomena is pointed out, and linked to other relevant parameters, such asthe radius ratio R and the Prandtl number, Pr. Although most of the relevant literature is on 2D cases, theeffect of the third dimension is considered as far as possible. Studies on the influence of the eccentricityof the inner cylinder on the laminar flow and the thermal asset are also reviewed. Finally, open questionsand topics for future research are hinted at.
