 |
|
As we all know Q=VA, i.e. volume flow is equal to the area perpendicular velocity vector times that x-section area. Here we see the velocity vectors as out put.
It would be most helpful to help support AIRNET calculated natural ventilation rates, if one could somehow output the net air change rate in the zone, from the CFD calculation. |

Hi Jean,
In order to derive zone air change rates, all you need to do is to combine any specified supply diffuser air volumes and any opening air flow rates entering the zone (which you can obtain from the Tools->CFD Boundary Conditions dialog) with the zone volume included in the CFD calculation. i.e. ac/hr = (3600 x supply volume flow rate in m3/s) / zone volume in m3.
Regards,
Steve |
