Hello, everyone. could you help me…

I would like to generate FCC reactor Stripper and Regenerator, both reactor has a nozzle or flow inside a reactor, please help me how to make flow inside the reactor.

I would suggest using the point sources. You can place them in any fluid cell and give a direction. You could also use pipes and small orifices to move the gas from the domain boundary to the injection location, but you will end up with high velocity gas in those pipes that will limit the simulation speed.

As an example, in this CFB I did, I used normal BCs at the domain edge for the coal injectors, but used point sources for the loop seal aeration.
