Abstract

Laminar boundary layer equations around an axisymmetric body of revolution in a mixed convective mode of heat transfer is solved. The body may be in a rotation and the results are presented
for the particular case of a sphere in rotation. In addition, the effect of inspiration is considered. Numerical results are obtained using the implicit Keller-Box method. In this method, parameters which are indicative of mode of the heat transfer , rotational speed (RP), local skin friction coefficient (SFP) and the local heat transfer coefficient (HTP) are obtained. The results of modeling the flow over the rotating sphere with surface inspiration show that the rotation of the body can delay boundary layer separation and reduces the friction coefficient to an angle of about 60°. The heat transfer results indicate that with increasing the rotational speed, the heat transfer coefficients are reduced.
