Similarity Solution in the Study of Flow and Heat Transfer Between Two Rotating Spheres with Constant Angular Velocities.

The similarity solution of the steady-state motion and heat transfer of a viscous incompressible fluid contained between two concentric spheres, maintained at different temperatures and rotating about a common axis with different constant angular velocities, is considered. the resulting flow pattern, temperature distribution and heat transfer characteristics are presented for various cases. aside from the energy equation, the same results as previous works are obtained for navier-stokes equations, but with less computational complexities.
