Couple of questions about modelling bubblers

Question

Hi - I have a couple of questions about modelling bubblers:

1. AIRFLOW - in the ELCOM science manual, it says to use the airflow rate (m³/s) at the level of the diffuser not the free-air flow rate of the compressor. Is that the same in AEM3D? (i.e., I should allow for adiabatic compression).

2. If my bubbler extends over several model grid cells, can I specify this in the boundary condition file as per other boundary conditions? And if so, are AIRFLOW and N_PORTS the total for the aerator (not per cell)?

Kind regards

David 

Answer 1

Hi David,

1) Yes airflow is still at the level of the diffuser

2) This is correct, AIRFLOW and N_PORTS the total for the aerator
