this is my second and finally question about flamelet model (i hope so!) and here i go:

i have underestood that flamelet its a finite rate chemistry approach? and no infinitely fast chemistry , correct me if im wrong... so i want to know if im correct with this:

flamelet model is based on the "primitive variable method":species mass fractions and temperature balance equations are no longer required and mean reaction rates wk are not modeled.Rans code solve only for flow variables(rho,ui,..)and mixture fraction variables(z,z2..) to estimate directly or indirctly the probabilty density function p(z*).

that's is correct for the flamelet combustion model??
here i plott some picture to resume all of this.





pleaseeeeeeee i really need to know all of this, my head gona bloww for all the night's studing and studing.
thanks very much
best regards
