  5. 5. Flamelet modelling of soot formation in diffusion flames

    University dissertation from Fire Safety Engineering

    Author : Anne Simone Dederichs; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Emissions; Pollution; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar diffusion flames than in turbulent ones. READ MORE
