[fasi]

Hello everyone,

I've been working on a simulation of a micro pump, which exhibits both laminar and turbulent flow regimes. For this reason, I've chosen to use the SST Gamma-Theta transitional turbulence model in CFX. Although I know that the model was primarily validated with freestream airfoil cases, it seems to produce reasonable results for my specific application.

However, there's one aspect that puzzles me: the values of turbulent intermittency in my simulation range from 0 to 2. According to the literature, intermittency should only vary from 0 (indicating laminar flow) to 1 (indicating turbulent flow). So, how should I interpret the intermittency values that exceed 1?

I appreciate any insights you can offer.
