Viscous flows in a concentric annulus with rotating inner cylinder is characterized by Taylor-Couette flow. When the annular gap is formed by the inner conical cylinder submerging in a cylindrical vessel, the effect of imbalance of centrifugal force dominates the flow field as well, while the basic flow, rather than the Taylor vortex, having 3D structure appeared even at rather high angular velocity. This paper describes convection patterns and their transitions appeared in the annular gap confined by conical rotor and cylindrical vessel under non-isothermal operations.
