Aerosol reactor design: Effect of reactor geometry on powder production and vapor deposition

Abstract

Production of Knudsen aerosols from gaseous precursors in the absence of coagulation is analyzed in reactors with laminar flow. Tubular, annular and parallel plates configurations are considered. Annular and parallel plate reactor geometries can produce more monodisperse aerosols than tubular reactors at the expense of lower yields. For equivalent conditions, these geometries give more vapor deposition and lower rates of particle formation than tubular reactors, a result of importance in chemical vapor deposition.
