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 ow 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. https://scientiairanica.sharif.edu/article_3229_85ae750ad1dbdc5c2703bcfe97e77152.pdf
