Abstract

The scaling relationships required to model the dispersion of a buoyant plume in a convective flow have been developed, in particular a modified Froude number has been used which maintains a correctly scaled path for the plume and kinematic similarity between the vertical convective and longitudinal free-stream velocities. Scale models of atmospheric convective boundary layers have been developed in the new Monash University Environmental Wind Tunnel and examples of the characteristics of the largest scale, 1 100, are presented, in particular observing the spectral distributions of the longitudinal and vertical velocity components with increasing convection.
