Abstract
This paper presents the results of an experimental study of natural convection heat transfer from a discrete thermal source located on the wall of a vertical channel. This configuration has both an unheated inlet and outlet region and produces a confined wall plume, which rises between the parallel plates that form the channel walls. In the present study, a thermal source of length was located on one wall of a vertical channel formed by two plates of length L separated a distance b. The thermal source was located a distance x along the plate was measured from the leading edge of the source. A dimensional analysis for this problem indicates that the local Nusselt number Nu{sub x} can be correlated in terms of the local Rayleigh number Ra{sub x}, the Prandtl number Pr, a dimensionless distance x/l, and three geometric ratios L/l, d/l, and b/l.
