Hello,

I have a question regarding Reynolds numbers.

As I understand, the higher a Reynolds number, the more turbulent a flow becomes, with Re>4000 considered turbulent.

I have a model where I've calculated a Reynolds number of 10^7, and when going to set my model boundary conditions I'm asked for a 'Turbulent Intensity' parameter, so I do some research and find the following equation:

I=0.16*(Re)^-1/8

So my question is, why does the turbulent intensity decrease as the Reynolds number increases, when a higher Reynolds number flow is meant to become more turbulent?

For my calculations I got a turbulent intensity of around 2%, which seemed far too low!
