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.
