THE RISE MODEL OF BUOYANT PLUME LIMITED BY MECHANICAL TURBULENCE

This paper has investigated the rise of bent-over buoyant plume in neutral condition.By means of the combined-effect model proposed at earlier time,authors have deduced a formula of final rise limited by mechanical turbulence and therefore have concluded that the corresponding formula neglecting the accumulated effect of ambient turbulence is only its particular case.By analyzing the function relation of the various affecting factors with the plume rise in the existing equations,it is proved that the formula derived from the combined-effect model is the most reasonable and shows more conformity to the observations.
