kOmegaSST for Water Analysis
 

Hey Foamers,

I'm currently concerning myself with the analysis of geometries flying in water. I'm wondering if I calculated the right values for turbulentKE and turbulentOmega.

For a velocity of vInfinity = 11.11 m/s I calculated:
turbulentKE = 0.004628
turbulentOmega = 30858

The results for the drag are unexpected high.

can you help me, checking if I took the right values?

thank you very much
Raoul

Hi,

It's impossible to diagnose the issue without more information - see here:

By assuming common values it seems to me your inlet TKE level is OK but the omega values seems a bit high. I recommend this site for quick summary of common estimation methods:

All the best,
