Abstract:Nusselt number is presented as a function of Reynolds number and Prandtl number (Pr) for a laminar flow about a non- rotating and rotating sphere. The sphere rotation is expressed in terms of Taylor number. Pr is ranging between 0.7 and 0.2. The governing equations were solved numerically using finite difference method for constant wall temperature and constant heat flux conditions. Received on 17 October 1996
