Abstract

Aerosol processes often are modeled using the population balance equation (PBE). This article presents a study on the simulation of particle size distribution during nanoparticle growth with simultaneous chemical reaction, nucleation, condensation and coagulation. The method used to reduce the population balance model is the method of moments. Under the assumption of lognormal aerosol size distribution, the method of moments was employed to reduce the original model into a set of first-order ODE’s (ordinary differential equations) that accurately reproduce important dynamics of aerosol process. The objective of this study is to investigate if we can use the reduced population balance model for the control of nanoparticle size distribution. The numerical result shows there is a dependence of the average particle diameter on the wall temperatures and the model can thus be used as a basis to synthesize a feedback controller where manipulated variable is the wall temperature of the reactor and the control variable the aerosol size distribution at the outlet of the reactor.
