Experimental permeability was the same for samples with 5% and 30% of additive. However, relative permeability of the fly ash sample (P r = 0,973) suggested only a slight decrease in permeability WebSep 7, 2016 · A prediction model for it is presented based on capillary pressure model, and the J-function prediction model is a power function instead of an exponential or polynomial function. Relative permeability is calculated with the J-function prediction model, resulting in an easier calculation and results that are more representative.
