1. 1. Development of Transient Flamelet Library Based Combustion Models

   Författare :Harry Lehtiniemi; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; auto-ignition; conditional moment closure; Tabulated chemistry; flamelet; spray; non-premixed combustion; Fysicumarkivet A:2012:Lehtiniemi;

   Sammanfattning : Three different methods for Reynolds-averaged Navier-Stokes computational fluid dynamics modeling of non-premixed ignition and combustion using tabulated chemistry have been developed. All methods make use of flamelet libraries, where the flamelet auto-ignition process is parameterized using a progress variable. LÄS MER

3. 2. Mathematical Modeling of Turbulent Reactive Flows

   Författare :Mikael Mortensen; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PMF; CFD; probability density function; chemical reactions; presumed mapping function; PDF; conditional moment closure; turbulent mixing; computational fluid dynamics; CMC;

   Sammanfattning : The purpose of this thesis has been to study and develop mathematical models of non-premixed turbulent reacting flows. The models developed can be used both by the chemical process industry and for turbulent combustion applications. Furthermore, the models are general and not developed for any specific chemical or mechanical system. LÄS MER
