Abstract: A numerical investigation of the flow and heat transfer of air in the annulus be-tween horizontal concentric cylinders with one cylinder heated and rotating is carried out.The mechanism of the suppression of natural convection by fluid rotation is advanced.It is proved that the convection heat transfer can be regarded as a conduction problem with heat sources(orsinks).

Key words: mixed convection, natural convection, rotating flow
