Source/Sink question

Riham

Hi everybody,

I am new fluent user and fluid dynamics beginner.

My model has a simple geometry (cubic box with an airflow inlet at constant temperature, constant velocity, and an airflow outlet)

I have to add a source/sink of a periodic airflow (at very low velocity) inside this box. Each half of period this source acts as a sink. It is also responsible of a litte rise of temperature and water vapor production within the box for longue term.

what should I do to model this source/sink with fluent? the general steps or any references please.

should I consider the energy equation?

I need your help.

Thank you very much in advance.
