Laminar Freee Convection from a Non-Isothermal Horizontal Cylinder
Abstract
Laminar free convection from a non-isothermal horizontal cylinder is analysed. The wall sur face temperature is assumed to be varied in the manner of a sub 1 (x/R) squared a sub 2 (x/R) to the 4th power. Special transformations are devised and employed so that the resulting differential equations and boundary conditions are free of the parameters a sub 1 and a sub 2. These differential equations are solved once and for all; solutions to the original equations for any particular values of a sub 1 and a sub 2 may then be read off easily as linear combinations of the numerical solutions given here. It is found that the dependence of heat transfer from a horizontal cylinder on Prandtl number is practically the same as that from a vertical plate. Furthermore, the heat transfer is greatly influenced by the surface temperature variations.
