How can I set an air flow network to simulate a solar chimney which depends on buoyancy effect ?

edit

THE DOCUMENTATION OF AIR FLOW SAYS IT CAN SIMULATE Dependence of air flow on buoyancy effects and wind pressure SO WHAT KIND OF SETTINGS I HAVE TO ERECT TO SIMULATE A DEVICE THAT WORKS WITH BUOYANCY EFFECT .

Yes, the airflow network does simulate buoyancy effects, but so does the ZoneThermalChimney object (see the engineering reference documentation). They just won't work together. You can potentially describe the thermal chimney as a separate, stacked zones in the airflow network, but if you only need to simulate the buoyancy in the chimney you should use the ZoneThermalChimney object.

i dont want to integrate the thermal chimney object with the air flow network , actually I model a cube like the solar chimney in the ecotect software then I insert the idf file to the enregy plus and now I would like to set the air flow net work to simulate the cube as solar chimney but I dont know what kind of settings it needs .

it is important for me to simulate the buoyancy effect in the airflow net work .

thanks !

You can follow some of the suggestions mentioned in this post about how to stack zones to account for stratification related to the buoyancy effect, but there are caveats to all of the approaches, including the examples with the AirflowNetwork.

Did you manage to set it up @BRIAN?

I HAVE THE EXPERIENCE OF THERMAL CHIMNEY MODULE BUT I WANNA MODEL IT WITH AIR FLOW NETWORK SO PLEASE GUIDE ME TO SET AIRFLOW NET TO AFFECT THE BUOYANCY DEVICE THANKS .
