Abstract:
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.
