Abstract
Laminar air flow combined convection in a vertical annulus with a constant temperature rotating inner cylinder is treated on the basis of a developing flow model, and the basic differential equations are rewritten in finite difference form and solved by a computer program in Fortran. Investigation covers the ranges of 0.2≤N≤0.9 , –300≤Gr/Re≤800 and 0.2≤Re2/Ta≤1000. In addition to the usual heat transfer calculations, this enables the developing velocity and temperature fields to be studied. On the other hand , the effect of a superimposed aiding or opposing natural convection on the developing tangential velocity profile is also investigated.
