Hello.
That paper was published on IAQVEC2010 conference(August 15-18,
2010, Syracuse, New York, USA).
(http://www.iaqvec2010.org)
But there is no download for full papers.
Best regards.

Subject: [EnergyPlus_Support] Re: Can Airflow Network simulate stack effect?
Thanks for your valuable answer, Lixing.
Even though stack effect has been validated with ASHRAE analytic solution, what
is the limitation in case of simulate DSF cavity flow?
Is it just not accurate in that AFN can't simulate the temperature
stratificaiton, or is there other reason exist?
When I made a DSF building with the AFN algorithm, the result seemed to pretty
well matched from air physical view(Comparing airflow rate and velocity of
lower part opening and upper part opening).
I have read the simulate DSFs with AFN algorithm published in ASHRAE
Transactions.
For example
http://www.bwk.tue.nl/bps/hensen/publications/02_ashrae_dskin.pdf
I wanna know the exact limitation of the AFN algorithm when I use it to
simulate DSF cavity flow.
Many more thanks in advance.
