turbulence intensities

hello I want solve the turbulence intensities, u',v' and w' but I did not find the corresponding variable disignation such for the normal stress u'2 (u2rs). I'm thankfully.

I am not sure that I understand your question, but you cannot solve for the fluctuations directly in PHOENICS. Rather they can be estimated in obvious ways from U2RS,V2RS, etc with the RSTM, or from KE with the k-e model. The INFORM facility can be used to deduce the fluctuations directly from solved turbulence variables.
