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: http://www.cfd-online.com/Forums/ope...-get-help.html. 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: http://www.cfd-online.com/Wiki/Turbu...ary_conditions All the best, Artur |
