Abstract
Aerosol measurement is used in different fields such as nanotechnology and materials science, environmental air pollution monitoring and air quality measurements, combustion and engine exhaust, inhalation toxicology and medical studies. One of the most prevalent methods for aerosol measurement uses electrical mobility. An electrical mobility spectrometer (EMS) is used to classify particles ranging from 10 – 1000 nanometers, under the influence of an electric field. There are two electrodes in EMS between which the aerosol and sheath air flow. Charged particles in the aerosol and sheath enter the device from one end and are subjected to an electric field. Passing through the annulus,...

Abstract
Aerosol measurement is used in a variety of fields such as nanotechnology, materials science, pollution monitoring, air quality measurements, combustion and engine exhaust analysis, inhalation toxicology, and medical studies. One of the most prevalent methods for aerosol measurement is to use electrical mobility. An electrical mobility spectrometer (EMS) is used to measure aerosol particles size distribution ranging from 10-1000 nanometers, under the influence of an electric field. The accuracy of this distribution is influenced by flow conditions, the geometry of the EMS, the electric field, and the number of electrode rings. In this work, a multi-channel EMS is studied using computational...
