How to Quantify Turbulence?

In CFD, turbulence intensity $(I)$ is an important parameter as its numerical value can be further used to calculate the turbulence parameters.

Mathematically,

$$ I~=~\frac{u^{\prime}}{\bar{u}} $$

$u^{\prime}~=~root~mean~square~(rms)~/~standard~deviation~(\sigma)~of~the~turbulent~velocity~fluctuations$ $at~a~particular~location~over~a~specified~time~period$

$\bar{u} = velocity~average~at~same~location~over~same~time~period$
