  2. 1. Single Fibre Collection Efficiency : Infångningseffektiviteten för ett fiber

    Author : Orest Lastow; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air filtration; collection efficiency; aerosol technology; numerical modelling; fibrous filter; fiberfilter; aerosolteknik; luftrening;

    Abstract : A personal computer program, FiFi, that makes a real-time two-dimensional simulation of the dynamic deposition process of particles on one or two fibres, has been developed. The code has been used to numerically calculate the collection efficiencies of spherical particles on a clean single fibre. READ MORE
