Calculating Turbulent Intensity

What is turbulence intensity and how is it calculated in Ansys Fluent software?

As an inlet boundary condition, you might want to use the turbulence intensity. It is often used as an index indicating the strength of the turbulence in the turbulence field.
Turbulence intensity is expressed by the percentage ratio of the flow rate variation with respect to the average flow rate (root mean square).
