Binary H2SO4-H2O homogeneous nucleation based on kinetic quasi-unary nucleation model: Look-up tables
[1] Recently, we have shown that the binary homogeneous nucleation (BHN) of H2SO4 and H2O can be treated as a quasi-unary nucleation (QUN) of H2SO4 in the equilibrium with H2O vapor and have developed a kinetic H2SO4-H2O nucleation model, which simulates the dynamic evolutions of cluster distributions explicitly. In this paper we present improved and updated version of the QUN model, which has ...
متن کاملUpdated H2SO4-H2O binary homogeneous nucleation look-up tables
[1] The calculated rates of H2SO4-H2O binary homogeneous nucleation (BHN), which is the only nucleation mechanism currently widely used in global aerosol models, are well known to have large uncertainties. Recently, we have reduced the uncertainties in the BHN rates on the basis of a kinetic quasi-unary nucleation (KQUN) model, by taking into account the measured bonding energetics of H2SO4 mon...
متن کاملQuasi-unary homogeneous nucleation of H2SO4-H2O.
We show that the binary homogeneous nucleation (BHN) of H2SO4-H2O can be treated as quasi-unary nucleation of H2SO4 in equilibrium with H2O vapor. A scheme to calculate the evaporation coefficient of H2SO4 molecules from H2SO4-H2O clusters is presented and a kinetic model to simulate the quasi-unary nucleation of H2SO4-H2O is developed. In the kinetic model, the growth and evaporation of sulfur...
متن کاملNucleation rate lookup tables based on improved quasi-unary H2SO4-H2O homogeneous nucleation and applications
The calculated rates of H2SO4-H2O binary homogeneous nucleation (BHN), which is the only nucleation mechanism currently widely used in global aerosol models, are well known to have large uncertainties. Recently in Yu (J. Chem. Phys. 127, 054301, 2007), we have significantly reduced the uncertainties in the BHN rates based on a kinetic quasi-unary nucleation (KQUN) model by constraining the mode...
متن کاملImproved quasi-unary nucleation model for binary H2SO4-H2O homogeneous nucleation.
Aerosol nucleation events have been observed at a variety of locations worldwide, and may have significant climatic and health implications. Binary homogeneous nucleation (BHN) of H2SO4 and H2O is the foundation of recently proposed nucleation mechanisms involving additional species such as ammonia, ions, and organic compounds, and it may dominate atmospheric nucleation under certain conditions...
