Hello everyone I am using Phoenics for studying wind environment in downtown area,
Could you please tell me which Turbulence model is better for evaluation of wind environment in downtown area?
I try to use the KEMMK in KE Variants, is that ok?
but i found it looks the same as KEMODL according the the constants in both of them,
also can i change the roughness parameter in the setting of this RANS model, i want to change it to 0.27 the same as i did in wind tunnel experiments.
Thank you very much for your help

The Kato-Launder & Murakami et al variants of the k-e model are reported to perform better than the standard k-e model for flow around buildings. Both are available in PHOENICS, and they are documented here:
The empirical constants of the standard model are retained, but differences arise in the modelling practices, i.e. modified production rate or eddy-viscosity relationship. The main issue is to improve the representation of irrotational strain.
Thank you very much it is very helpful
salut I want to enter the velocity like V=ax+b on a in a bubbly two phase flows
