2. 1. Numerical Modelling of Soot Formation in Turbulent Non-Premixed Flames

   Author : Olga Roditcheva; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motorer; Motors and propulsion systems; Teknik; Technological sciences; oxidation of soot.; soot; polutant formation; flamelet approach; Combustion; turbulence; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

   Abstract : This thesis describes an extended flamelet approach for modelling of soot formation in turbulent hydrocarbons diffusion flames. Detailed chemical kinetic mechanisms are used to compute species concentrations, temperature, density and soot formation rates as functions of flamelet coordinates in the space of mixture fraction and scalar dissipation rate.

4. 2. Acoustic separation and electrostatic sampling of submicron particles suspended in air

   Author : Ramin Imani Jajarmi; Etienne Robert; Lisa Prahl Wittberg; Laszlo Fuchs; Martin Wiklund; Klas Engvall; Jeremy Hawkes; Michel Cervantes; Mats Åbom; Olga Roditcheva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustic; separation; acoustophoresis; Engineering Mechanics; Teknisk mekanik;

   Abstract : We investigate experimentally the effects of acoustic forces on submicron aerosol in a channel flow. This technique can potentially overcome some of the limitations of conventional separation systems and provide advanced manipulation capabilities such as sorting according to size or density.
