AB In this work, we present novel results of the buoyancy driven flow between two concentric cylinders, when an azimuthal thermal gradient is imposed to the inner cylinder. To accomplish that, angular-dependent temperature distribution (sinusoidal function) is imposed at that surface so that a fourth parameter is added to the problem (L). This new parameter accounts for the ratio of amplitude of temperature (amplitude of sinusoidal function) in the inner cylinder to the difference of temperature between theinner and outer cylinder. When this new parameter is zero, one retains the same solutions shown in J.J. Serrano-Aguilera et al.[1] (isothermal conditions in both cylinders) but increasing this parameter, the imposed angular gradient in the inner cylinder  induces flow structure changes and the subsequent modification in the average equivalent conductivity.
