Purpose
– The purpose of this paper is to investigate competitive effect of source strength and coagulation on the evolution of aerosol size distribution with a continuous source.
Design/methodology/approach
– A theoretical model was proposed in which the nanoparticle population balance equation with respect to particle size was solved by the sectional method.
Findings
– It was found two modes appear when a nanoparticle system was injected by a continuous source.
Originality/value
– Through tracing the evolution of particle size distribution with different source strength, the characteristics of two modes as well as their lag-time to approach steady state were deeply investigated.
