Abstract

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.
