Abstract
  • Large Eddy simulation spectral data and Taylor statistical diffusion theory are used to obtain eddy diffusivities in a convective boundary layer. The derivation employs a fitting expression obtained from LES data for the vertical peak frequency. The vertical eddy diffusivities are well behaved and show similar patterns and magnitudes as those derived from experimental spectral peak frequency data. In addition, this new vertical eddy diffusivity was introduced into an advection diffusion equation which was solved by GILLT method and validated with observed contaminant concentration data of the Copenhagen experiment. The results of this new approach are shown to agree with the measurements of Copenhagen. (literal)
