Electrical charging of aerosol nanoparticles and sonne practical applications^
This review article summarizes the main results of recent fundamental research on the electrical charging of nanometer-sized aerosol particles (particle diameter below 10 nm, Knudsen number above about 15, kinetic regime). It covers topics of great relevance to aerosol processing and measurement, such as the effect of the presence of a number of ions on the surface of a nanoparticle on its elec...
متن کاملExperimental Study of Charging Efficiencies and Losses of Submicron Aerosol Particles in a Cylindrical Tri-Axial Charger
The object of the present work was to design, construct and evaluate a cylindrical tri-axial charger for charging of submicron aerosol particles by unipolar ions. The corona discharge characteristics, the intrinsic and extrinsic particle charging efficiencies, and the losses of aerosol particles were experimentally evaluated for particle diameters in the range between 50 nm and 500 nm under dif...
متن کاملAerosol charging state at an urban site: new analytical approach and implications for ion-induced nucleation
The charging state of aerosol populations was determined using an Ion-DMPS in Helsinki, Finland between December 2008 and February 2010. We extrapolated the charging state and calculated the ion-induced nucleation fraction to be around 1.3 %± 0.4 % at 2 nm and 1.3 %± 0.5 % at 1.5 nm, on average. We present a new method to retrieve the average charging state for a new particle formation event, a...
متن کاملElectrical Conductivity near the Earth’s Surface: Ion – Aerosol Model
An ion-aerosol model for the electrical conductivity of the lower atmosphere is developed. Input parameters to the model are ion-pair production rate, obtained from the concentrations of radon and its progeny; aerosol number density; and the meteorological parameters such as temperature, pressure and relative humidity are the input parameters to the model. Diurnal values of conductivity compute...
