Natural convection in horizontal annuli has been extensively studied by several investigators, mostly for isothermal cylinders. Only a few papers deal with a constant heat flux boundary condition on the inner wall. Natural convection of gases and liquids within horizontal cylinders has applications in thermal storage systems and transmission cables. The present study reports numerical and experimental heat transfer results and flow structure in horizontal annuli with the inner wall maintained at constant heat flux and the outer wall at constant temperature. Flow visualizations investigate the metastability and the three-dimensionality of the flow in the annulus.
