In this paper, the effects of suction and blowing on the temperature field between two eccentric rotating spheres which rotate about a common axis of rotation are presented. The angular velocity of outer sphere is constant and the angular velocity of inner sphere is considered as sinusoidal function. The Navier-Stokes and energy equations are solved by employing the finite difference method and implicit scheme. The resulting flow patterns and temperature distributions are presented for various values of the flow parameters including rotational Reynolds number , and a blowing/suction Reynolds number . In this work, the effect of viscous dissipation is ignored. The eddies created in the flow field are found as preventive means for heat transfer. Also, it is observed, where the distance between two spheres is reduced the diffusion of heat becomes more, because the Coriolis forces are bigger in these regions
