Defining two velocity inlets

hesamna · April 5, 2021, 16:57

When our model have two velocity inlets (with different mass flow rates) and one outlet, does fluent consider the face named Velocity Inlet as just inlet or how can we prevent the flow from exiting from inlet with less mass flow rate?

The faces can be named anything. They can be named velocity inlet or velocity outlet or Joe. What matters is the type of boundary condition. If the boundary condition is the velocity inlet type, then it will be a velocity inlet. The names are just labels. Under the hood each boundary as a surface ID (a number) and the name that you declare is just for you.

You may have any number of velocity inlets (even over 9000).
