摘要：

Numerical and analytical solutions of the turbulent diffusion equations were obtained for paniculate transport within and above a foliage canopy when advection was neglected. By considering deposition of particulates with diameters, dP, in the range 5-300 μm, it was demonstrated that predictions of deposition velocity using analytical approximations agreed closely with those obtained by numerical solution. The analytical model appeared to be particularly useful for predicting the deposition characteristics of small particulates (dP < 10μm), but was less successful in predicting the in canopy" concentration profile for larger particulates. © 1979."
