Plane turbulent wall plumes, caused by sources of buoyancy along walls, are frequently encountered in unwanted fires within structures. Motivated by this observation, the present investigate extended recent measurements of turbulent round and free line plumes in this laboratory to consider plane turbulent wll plumes using similar methods. Only weakly-buoyant turbulent wall plumes along smooth plane vertical surfaces with conserved buoyancy flux were considered; this implies flow along an adiabatic wall for a thermal plume. The present study emphasized conditions far from the source where source disturbances and momentum have been lost.
