Predicting the settling velocity of flocs formed in water treatment using multiple fractal dimensions

A Vahedi, B Gorczyca - Water research, 2012 - Elsevier
Here we introduce a distribution of floc fractal dimensions as opposed to a single fractal
dimension value into the floc settling velocity model developed in earlier studies. The …

Entropy analysis of in situ particle size spectra

OA Mikkelsen, KJ Curran, PS Hill, TG Milligan - Estuarine, Coastal and …, 2007 - Elsevier
