Dear users,<br>I still have no idea how to simulate buoyancy airflow between the airnodes of the atrium. <br>COMIS and CONTAM are based on orifice model to calculate airflow through windows or cracks but there is no orifice between each airnode of the atrium model, only virtual planes... <br>
Is it better to simulate the atrium as one zone with one airnode ? What is then the interest of multiple airnodes ?<br><br>Thanks,<br><br>Best regards<br>Ewen<br><br><div class="gmail_quote">2011/8/5 Martin Pichler <span dir="ltr"><<a href="mailto:martin.pichler@tugraz.at">martin.pichler@tugraz.at</a>></span><br>

Hello,<br>
<br>
for the simulation of sensitive thermal coupling u either have to
use the coupling between neigboring zones directly or u use Type 56
with TRNFLOW. The latter will be mor accurate but more demanding in
terms of input parameters.<br>
Maybe my colleague can tell u more about that.<br>
<br>
Best rgards<br>

I'm currently trying to simulate an atrium. I'm using trnsys3D and
the atrium's zone is divided in 6 airnodes.<br>
I use the detailed model for radiation and I expect to simulate
the stratification of temperature.<br>
<br>
The results I have are not completely satisfying.<br>
Is there any convective exchange between each airnode of a same
zone or are the convective zones closed for each airnode ?<br>
Does anyone has an idea on how to simulate buoyancy air flow in
the atrium ?<br>
<br>
Another question is : is it possible to have a zone with multiple
airnodes and to use a standard model for radiation calculation ?
it is not so clear to me in the MultizoneBuilding manual.<br>
<br>
Best regards,<br>
