Abstract
A theoretical investigation was made of the steady laminar thermal plume resulting from a line heat source located along the base of an adiabatic vertical wall. Velocity and temperature profiles are determined, including consideration of variable fluid properties, for Pr = .01, .1, .7, 1, 10 and 100. The results are compared with unconfined laminar line plumes having the same energy flow per unit length in their half-width as the wall plume. It is found that the wall plume has a lower maximum velocity and a higher maximum temperature than the corresponding free plume. The wall plume is also somewhat thicker than the half-width of the free plume.
