Hi all,
What is the difference between mass-flux boundary condition and mass-flow rate inlet boundary condition in fluent? they seem to be similar I am using fluent 19 Thanks, |

apparently it does not make any difference according to my research.
Please correct me if I am wrong |

I found the answer to my own question. Thought I post it here, in-case someone else has the same question
If a total mass flow rate is specified, ANSYS FLUENT converts it internally to a uniform mass flux by dividing the mass flow rate by the total inlet area. If the direct mass flux specification option is used, the mass flux can be varied over the boundary by using profile files or user-defined functions. If the average mass flux is also specified (either explicitly by you or automatically by ANSYS FLUENT), it is used to correct the specified mass flux profile |
