Evaporation and growth of multicomponent aerosols laboratory applications

Abstract

Design equations for two types of devices used in aerosol growth and evaporation studies, the well-mixed vessel and the diffusion dryer, are developed and their use demonstrated for aqueous salt solution particles. The results of several common simplifying approximations are evaluated. An approximate method for determining residence times required for drying particles that exhibit a hysteresis effect, accurate to within several percent for the cases considered, is suggested. © 1987 Elsevier Science Publishing Co., Inc.
