Hi. The equation for calculating turbulence intensity at the inlet is 0.16(Re)^-1/8 . For my problem of tidal turbine simulation, i have an RE value of 10.16x10^5. Substituting this value in above equation i get the value for Turbulence intensity equal to 0.0283. I want to know this value of 0.0283 is already in percentage or the turbulence intensity in percentage will be 2% ?

It means that the turbulence intensity is 2.83 %.

so for my equation for determining the turbulent kinetic energy which is 3/2(UI)^2, which value of Turbulence intensity should i use - 2.83 or 0.0283? |

If your turbulence intensity is 2.83%, you should use I=0.0283 in 3/2(UI)^2 to get k.
