Molecular dynamics simulation is carried out to investigate ion-induced nucleation in water vapor. Comparison is made between ions with similar size and opposite electric charge, a potassium ion and a chloride ion. At large supersaturation ratios, no qualitative difference is discernible in clustering dynamics. At a small supersaturation ratio, clustering around the cation stops at a size ∼12, while clustering around the anion continues. The molecular structure of ion clusters explains the difference.

    A modal atmospheric aerosol model (M7) is evaluated in terms of predicting marine new particle formation and growth. Simulations were carried out for three different nucleation schemes involving (1) kinetic self-nucleation of OIO (2) nucleation via OIO activation by H2SO4 and (3) nucleation via...

    At elevated temperatures, droplet growth becomes very fast. We present a new method to generate a nucleation pulse using a shock tube. This method is particularly suitable for nucleation and growth studies at high-temperature conditions, because the falling edge of the nucleation pulse is very...

    A new method for changing the supersaturation in the Turbulent Mixing CNC has been developed and used to study the influence of composition and vapor properties on heterogeneous nucleation. Supersaturation was controlled by changing the condensing vapor pressure in nozzle flow by saturating only...
