Can RMS velocity even be smaller than mean velocity? |

Dear all,
I'm using the mixture, k-e, air-water two phases model in FLUENT to simulate bubble column. I calculated with transient mode. After calculation, I checked the results: RMS velocity magnitude and mean velocity magnitude. I found out that RMS value is even smaller than mean value. Does anyone know how can it be like this? Is there anything wrong? Thanks a lot. |

Some links are shared here, where you can find the discussion about the RMS velocity
