Detailed Description

Evaluates and writes the turbulence intensity field 'I'.

The turbulence intensity field 'I' is the root-mean-square of the turbulent velocity fluctuations normalised by the local velocity magnitude:

$I \equiv \frac{\sqrt{\frac{2}{3}\, k}}{U}$

To avoid spurious extrema and division by 0 I is limited to 1 where the velocity magnitude is less than the turbulent velocity fluctuations.

Example of function object specification:

functions
{
    .
    .
    .
    turbulenceIntensity
    {
        type        turbulenceIntensity;
        libs        ("libfieldFunctionObjects.so");
    }
    .
    .
    .
}

or using the standard configuration file:

functions
{
    .
    .
    .
    #includeFunc turbulenceIntensity
    .
    .
    .
}
