Uncontrolled fires produce flames where the initial momentum of the fuel is low compared with the momentum produced by buoyancy. The heights of such flames with wood as the fuel are examined and discussed in terms of both a dimensional analysis and the entrainment of air into the turbulent flame. They are then compared with other experiments on the flow of hot gases. Some recent experiments on the effects of wind on such flames are also reported.
