Abstract
A solution is obtained for fully developed flow of a constant-property fluid, with the lowest temperature equal to the fluid bulk temperature. This is satisfactory only for low values of Rayleigh number, up to about 20, that is, for relatively long cylinders. A second solution has in addition a thermal entry region, for application to shorter cylinders, to the point where the entry region fills the cylinder. This solution has not yet been made mathematically exact. Nusselt numbers up to the terminal point, at Rayleigh number of about 16000, are identical with those for the finite difference result of Dyer {6}. © 1976.
