Validation of a new level set approach in the counter flow premixed flame
The flamelet model based on the concept of local flame speed S*is newly developed to describe a premixed flame with a finite thickness when defining G as the non-dimensional temperature. In the previous work the new flamelet model was validated by 1-D steady premixed flame successfully. In this pape...

| description | The flamelet model based on the concept of local flame speed S*is newly developed to describe a premixed flame with a finite thickness when defining G as the non-dimensional temperature. In the previous work the new flamelet model was validated by 1-D steady premixed flame successfully. In this paper the model of 3-D counter flow premixed methane-air is investigated. The local flame speed can be proposed as S*=Su+2Su(G-G0) where the scalar G=G0 represents the flame surface in the flamelet model. Considering the stretch effect the expression for the modified burning velocity is Su=Su0-Su0Lκ where Su is smaller than the burning velocity of the unstretched flame Su0. The new flamelet model results are compared with the original G-model results in the velocity and the temperature profiles. The results are also validated by the detailed chemical reaction solution of GRI-Mech3.0 by CHEMKIN. |
