Abstract
It is pointed out that during the diffusive relaxation of a spatially inhomogeneous aerosol, the difference in particle coagulation growth rates in regions with different particulate volume fractions will result in a modification of the corresponding local particle diffusion coefficients. This in turn will lead to a decrease in the rate of relaxation of the aerosol, and results are derived for this modified relaxation, for aerosol particles with both compact and fractal structures in the regimes Kn >1. In the case of fractal particles with Kn>>1, the modification is sufficiently strong for a spatial inhomogeneity in volume fraction to increase with the passage of time over a restricted time interval. A calculation of numerical values suggests that, if experimental difficulties could be overcome, measurement of aerosol relaxation could provide useful information on particle structure and coagulation effects.
