We review the models and numerical methods used in flame reactor for the modeling and simulationudof nanoparticle. And we also review the control of nanoparticle size distribution, some nonlinearudcontrol strategies were looked into. A general model in which nanoparticles form in gas phase andudgrow through chemical reaction, nucleation, condensation and coagulation is discussed. Particlesuddispersed in a fluid move randomly, due to Brownian motion, and, along their trajectories, theyudcollide with each other. The model is formulated in terms of a detailed population balance whichuddescribes how aerosol size distribution evolves with time. For this population balance models audnumber of different numerical approaches exist. We reviewed sectional, finite element and MonteudCarlo methods, method of moments
