On the rise of buoyant plumes in turbulent environments

  • Author(s) / Creator(s)
  • A plume rise model is derived from the equations of turbulent motion, retaining the turbulent flux terms. The solutions are similar to those proposed earlier by Csanady but containing an exponential decay term. The model finds particular value in predicting a leveled-of£ plume trajectory in neutral atmospheric conditions. In unstable atmospheric conditions the ultimate mode of behavior depends on whether the atmospheric turbulence or the unstable stratification finally dominate the plume motion.
