A Review of Experimental Data of Vertical Turbulent Buoyant Jets,

摘要

Experimental data are reviewed critically of vertical turbulent buoyant jets issuing into calm neutral or stably stratified environment. Both plane and axisymmetric jets are included and the whole Froude number range from the pure jet to the pure plume is covered. Similarity and scaling laws are introduced and the experimental data are interpreted according to these laws. Measurements of the following quantities are reviewed:rate of spread,lateral profiles of velocity,temperature or species concentration,velocity,temperature or concentration along the axis of the jet,and turbulent quantities such as fluctuating velocity and temperature and turbulent shear and heat fluxes. The measurements of various experimenters are compared and examined for their reliability;and the most reliable data are identified.
