Development and Validation of a Turbulent Flame Propagation Model
(2011) FYSM31 20111Department of Physics
- Abstract
- The aim of this thesis was to develop a model for flame propagation, to implement in a zero-dimensional engine simulation tool (DARS 0d-SRM) which previously only used fitted Wiebe-functions to describe the flame propagation. The idea was to create a model which could replace or complement the Wiebe function, but with predictive capabilities,
avoiding the need to perform curve-fitting when certain parameters are changed.
In addition to selecting and developing a suitable mathematical model for calculating the turbulent flame propagation speed, the project also included developing a suitable model for calculating the flame volume for a given flame radius. To achieve maximum precision, a Monte Carlo model was created for this purpose.

The flame propagation model was validated against an earlier study, and against two sets of experimental data. Good correlation was found. (Less)
