Turbulent intensity in Tecplot
 

I am trying to draw Turbulent intensity contours in tech plot.
I have tried it by doing writing equation as

{intensity}=sqrt({Turbulent Kinetic Energy})
{intensity/uavg}=({i}/22.72)


where,
Uavg = average velocity


But not able get correct contour as compared to contours seen in Fluent.


Pls help

You can export solution data of Turbulent intensity in Fluent, then import to Tecplot

hi dear friend
 

to get ur ideal contour u should define a turbulence term in fluent software and it depended on the type of ur problem.
High-turbulence case: High-speed flow inside complex geometries like heat-exchangers and flow inside rotating machinery (turbines and compressors). Typically the turbulence intensity is between 5% and 20%
Medium-turbulence case: Flow in not-so-complex devices like large pipes, ventilation flows etc. or low speed flows (low reynolds number). Typically the turbulence intensity is between 1% and 5%
Low-turbulence case: Flow originating from a fluid that stands still, like external flow across cars, submarines and aircrafts. Very high-quality wind-tunnels can also reach really low turbulence levels. Typically the turbulence intensity is very low, well below 1%.
in simulation often u should enter a percent as turbulence intensity.tell me about ur problem;)

The right hand side of the first equation should change to
sqrt({Turbulent Kinetic Energy}*2.0/3.0).
It affects the value of TI but the contour should look similar. Also, the r.h.s of the second equation should change to ({intensity}/22.72). Do you happen to have a variable named "i" in your file?
