Mmixture Fraction/PDF Modeling Approch


There an other way to simulate chimical reactions.

In the simulationg using directely fluent/uns the solutoin may not converge. espicialy when it's about a reaction wich have different time scales : phenomas hapens in both large and smal scales.

fast reactions for example have convergence problems. this kind of reaction can be done with a preprocessor called prePDF.

The mixture fraction/PDF modeling approch is used for example to simulate turbulent diffusion flames.
