VFR (Q) boundary condition
Hi all dears,
I want to use VFR boundary condition in my simulation. In fact i want to use a volume flow rate such as a pump to exit flow in my domain with distinct flow rate. could you pleas, how i can do it? |

hi
flow-3D V.10.0.1 thank you |
This can be done in two ways. Either a mesh BC or a mass sink. A mesh BC is simply defined at the mesh edge, choose VFR BC, set the flow rate, set the direction of the flow - done!
A mass sink is defined using a geometry component. Define the component (e.g., a disk), and set its flow rate to a negative value. Michael Quote:

hi, prof. michael barkhudarov
thank you for your reply, but in VFR BC, you can only enter flow into domain not exit from domain. we can only determine direction of entering flow to domain not exiting flow from domain. |

Thank you for your reply, my problem solved. I have another question: It is possible to draw 2D streamline in flow3D, similar to 3D streamline? best wishes |
I don't think so
