Abstract. The similarity solution of the steady-state motion and heat transfer of a viscous incompressible
uid contained between two concentric spheres, maintained at dierent temperatures and rotating
about a common axis with dierent constant angular velocities, is considered. The resulting
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.
