• This paper is concerned with developing natural convection in an open-ended vertical annulus with two rotating boundaries and a uniformly heated inner wall. The governing equations have been numerically solved; the obtained results show the effect of a rotating outer boundary on the developing tangential, axial and radial velocity profiles and the pressure distribution across the annular gap. Also, results are presented to clarify the effect of the outer cylinder rotation on the temperatures of the two walls and the relationship between the annulus height and the volumetric flow rate. For the special case of a stationary outer cylinder, the development of the tangential boundary layer displacement thickness in an annulus of radius ratio 0.9 is given, so that Astill's stability criterion can be utilized.
