CFD Modeling of nanoparticle formation in a plasma synthesis reactor
… metal powder formation in a Inductively Coupled Plasma reactor. A carrier gas transports the metal powder into the reactor in where it attains the vapor phase. The products are recovered after a quenching process. The model accounts for particle formation by nucleation and growth by condensation …
