Hi everyone,

I am doing my FYP with studying the kitchen ventilation system. I have few questions when I set the boundary condition.


As the figure show, the blue part is the inlet, red part is the outlet and other is the duct and the body of the ventilator.
The cubic near the outlet is the exhaust fan.

The model is k-epsilon. I set the inlet and outlet are pressure-inlet and pressure-outlet respectively. Is it correct? Also how can I set the turbulence with correct parameter? Furthermore, is there any other things I need to set?

Here is the spec. for the exhaust fan:

Exhaust Fan

Dimension 970W x 780L x 800Hmm

Dia 15inch
Duty 2.2kW
Electrical 380V50Hz 3phase
Pressure 406 - 387Pa
Flow rate 5818 to 12544m3/h
rpm 930rpm
Wt. 148kg


Please help me, thank you
