  1. 1. Modelling effects of flame development on stationary and oscillating premixed turbulent combustion

    Author : Pratap Sathiah; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame development; Keywords: Premixed turbulent flame; Flame Speed Closure model;

    Abstract : The vast majority of contemporary models of premixed turbulent flames applied to multi-dimensional RANS numerical simulations of combustion in gas turbine engines and aero-engine afterburners focus on fully-developed flames, characterized by fully-developed turbulent diffusivity, thickness, and burning velocity. However, abundant experimental data obtained from statistically stationary premixed flames clearly show that a typical turbulent flame develops as it is convected by mean flow from a stabilization zone.

  2. 2. Wall Related Lean Premixed Combustion Modeled with Complex Chemistry

    Author : Johan Andrae; KTH; []
    Keywords : Wall effects; premixed flames; flame quenching; numerical modeling; chemkin; boundary layer approximation; gasified biomass; fuel-NOx; hybrid catalytic combustor.; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Increased knowledge into the physics and chemistrycontrolling emissions from flame-surface interactions shouldhelp in the design of combustion engines featuring improvedfuel economy and reduced emissions. The overall aim of this work has been to obtain afundamental understanding of wall-related, premixed combustionusing numerical modeling with detailed chemical kinetics. READ MORE
