Hi, Everybody............

Does some one know, that which model LES is using to calculate SGS scalar variance i.e Mixture fraction variance.

Regards

with LES the weller model is really good. it is flame area model tracking mixture fraction.

For subgrid scalar variance( i.e mixture fraction variance for PPDF), there are 3 models which are being used mostly in literature, scalar similarity model, or dynamic model ( these are similar to smagorinskey models for momentum equation) and a transport equation with modelling the scalar dissipation rate. I did not find any where , where we can mention these models and its coefficients.
