gRomK13 New Member Join Date: Jul 2009 Location: near Marseille, France Posts: 7 Rep Power: 16	I still would like to have some further explanations about the formula $I=0.16 \cdot Re^{-1/8}$ (turbulence intensity in a fully developped pipe flow) which I quoted in my previous post. - How comes the turbulence intensity decreases when mean velocity gets bigger? Would it be that fluctuations are smoothed when a flow becomes faster? - What range of Re this expression if valid for? I cannot believe turbulence intensity exceeds 6% for laminar flows....! Thank you in advance
