Dear colleagues and CFD experts
Can anybody help me understanding the difference between the following quantities, which I thought should have been the same thing :P :
1. Turbulence Kinetic Energy
2. 0.5*(Velocity Correlation uu+Velocity Correlation vv+Velocity Correlation ww)

Solution data:
- Rotating frame of reference
- k-omega SST turbulence model

Thanks!
Bruno
