Application of two-thirds law to plume rise from industrial-sized sources

Rittmann, Bruch E.

Abstract Plume rise measurements from industrial-sized sources (F < 100m ⁴ sec ⁻³), including those experiencing stack-tip downwash, were compared to the plume-rise predictions from the $“ 23 law”$ . When stack-tip downwash was not significant, plume rises for sources having a buoyancy flux less than 100 m⁴ s⁻³ were typically 70–75 % of that predicted by the $23$ law. Plume rises for sources experiencing severe stack-tip downwash were on the average 44 % of that predicted by the $23$ law; however, most plume rises were 12 to 50% of the predicted values, and some were negative. Reduced rise and weakened correlation of rise with buoyancy flux indicated that factors other than buoyancy flux—such as downwash, increased entrainment, and turbulence controlled termination—significantly controlled plume rise.
