Abstract The stability of free convection in an annulus is governed by the boundary conditions on the inner and outer walls of the annulus and the upper and
lower boundaries. This paper explores the effect of free convection on the inner surface of the annulus, where the boundary conditions for the outer
wall and the upper and lower boundaries are controlled. The temperature is measured in the center of the air cavity and just below the surface of
the inner annular boundary. Experimental results are shown for a radius ratio of 0.40, aspect ratio of 20.7. More >
