Turbulence Intensity
$$
I \equiv \frac{u^{\prime}}{u_{a v g}}=0.16\left(R e_{D_{H}}\right)^{-1 / 8}
$$Turbulence Length Scale
$$
\ell=\frac{0.07 L}{C_{\mu}^{3 / 4}}
$$Turbulent Kinetic Energy
$$
k=\frac{3}{2}\left(u_{a v g} I\right)^{2}
$$Turbulent Dissipation Rate
$$
\varepsilon=\frac{k^{3 / 2}}{l}
$$
