Abstract

The transient motion and the heat transfer of a viscous incompressible flow contained between two vertically eccentric spheres maintained at different temperatures and rotating about a common axis with different angular velocities is numerically considered when the angular velocities are an arbitrary functions of time. The resulting flow pattern, temperature distribution, and heat transfer characteristics are presented for the various cases including exponential and sinusoidal angular velocities. Interesting effect of long delays in heat transfer of large portions of the fluid in the annulus is observed because of the angular velocities of the corresponding spheres. As the eccentricity increases and the gap between the spheres decreases, the coriolis forces and convection heat transfer effect in the narrower portion increase.
