A fully second-order closure model for turbulent reacting |
|
flows is suggested based on Favre statistics. For |
|
diffusion flames the local thermodynamic state is related |
|
to single conserved scalar. The properties of pressure |
|
fluctuations are analyzed for turbulent flows with |
|
fluctuating density. Closure models for pressure |
|
correlations are discussed and modeled transport |
|
equations for Reynolds stresses, turbulent kinetic energy |
|
dissipation, density-velocity correlations, scalar |
|
moments and dissipation are presented and solved, |
|
together with the mean equations for momentum and mixture |
|
fraction. Solutions of these equations are compared with |
|
the experimental data for high heat release free mixing |
|
layers of fluorine and hydrogen in a nitrogen diluent. |
