摘要
The fluid-dynamics approximation is used to present the flow dynamics in a non-isothermal aerosol reactor for silica nanoparticle production. Two flows are mixed in the reactor. One of them is plasma gas and raw substance vapour, the other is cooling gas. Different types of mixing are considered and their influence on the temperature variation in the reactor is shown. The process of homogeneous condensation induced by chemical reactions and fast vapour cooling is studied. The role of the vapour supersaturation for the particle growth process is investigated. The results concerning particle size distributions obtained by modelling are compared with experimental ones. (C) 2002 Elsevier Science Ltd. All rights reserved.
