A numerical study of three–dimensional, steady, turbulent and incompressible natural convection of air (Pr=0.72) within a rotating cubic enclosure is presented. The present code is based on solving partial differential equations for conservation of mass, momentum and energy equations for a rotating frame. The turbulence effect is introduced by using two equations turbulence model of k-e . Finite volume method is used in solving the governing equations. SIMPLE algorithm is applied to solve the set discretization equations. To verify the validity of present method, present results is compared with those of previous published work under the same conditions. The influence of changing rotation Rayleigh number (Rar ) as a result of chancing angular velocity of enclosure, and temperature difference of enclosure walls on the average Nusselt number (Nu) is presented and correlated.
