Hi,
I would like to know I'm using a periodic boundary condition so 1/10 of my cylinder is represented. By setting the turbulence parameters, do I need to set my hydraulic diameter to 1/10th of the full geometry or the full diameter itself? thank you David |

Could you explain why to use full diameter?
Thank you in advance |

FLUENT needs to have the hydraulic diameter to get an estimate of turbulent intensity. The size of the eddies is limited to the physical space available, and hydraulic diameter is a representative value.
