Hi everyone,
I did a simulation on Euler-Euler gas-liquid bioreactor and the result seems good. Afterward, i want to find the stagnant zone for liquid phase (the percentage of volume with low velocity per total volume). How can i discover the volume under certain velocity (lower than 10^-3 m/s)? I would be really glad if there are some suggestions Thanks |

Hi
I am still wondering how to find the volume of the stagnant zone and i think it might be possible to do that through expression in CFD-post. What would be a good way to do that in expression? I mean how to write the expression since there is no formula about it I hope someone can help me with this issue Regards |

Hey,
Would setting an iso-clip with your defined max velocity to create a surface, and then using surface integrals --> sum --> mesh --> cell volume to obtain a total volume work? You could then multiply this value with the average volume fraction (within the iso-clip) of your desired phase to obtain an approximate value, but I'm just guessing here. |
