January 26, 2021 at 5:16 pmmesakcaSubscriberI am trying to simulate an axisymmetric flow in a bubble column.nCurrently i have a cylindrical domain where gas is introduced from bottom (sparger covers whole bottom diameter) in vertical direction which is set as Z axis. My inlet bc is mass flow inlet and flow direction is normal to boundary. My outlet bc is degassing outlet.nIs this enough to represent axisymmetric pattern of flow, should i add any other (radial, tangential?) components of flow or fix something else?nThank you for your answers.nn

The axis aligns with y=0 and y must be greater or equal to zero. nIn the 2d-axi case you would only add swirl if there is any in the real case. That's fairly rare in columns as you're aiming for a uniform gas distribution to maximise the contact area. n
