# Contrib/turbFoamAverage with k-omega SST SAS

## Contents

## 1 k- SST-SAS Equations

### 1.1 References

## 2 Solver

The openFoam solver is a modified version of turbFoam. Since the k- SST sas turbulence model, in unstable flow situations, gives LES-like solution fields, the modifications were introduced to handle the omega field and to allow the time averaging of pressure and velocity quantities. The averaging has been done in analogy with the openFoam LES solver oodles.
