Numerical study for natural convection within a rotating cubic enclosure

Abstract EN

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, a present result 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.
