Modelling fouling induction periods [PDF]

open access: yesInternational Journal of Thermal Sciences, 2012
Abstract A fouling process is often preceded by an induction period in which no significant fouling is observed. In this paper, a simple lumped parameter model based on fractional surface coverage θ has been developed to correlate experimental data in the induction period.
