Vikram, others,
EnergyPlus models displacement ventilation or other underfloor systems with significant temperature stratification with a two-node room model developed by Paul Linden and others at UCSD, and Phil Haves at LBNL.

Suneel,
As far as I know, you cannot model stratification in eQUEST. There is a workaround with modelling underfloor systems (Dan Nall & Marlin Addison have done some work in this area - check the link here, or just google their names)

I am not sure that this is what you are looking for though. If you are modelling only stratification, you probably want to use CFD.
I am not familiar with Energy Plus, so I dont know if it does stratification modelling, but that might be an option thats cheaper than cfd.

I am modeling energy use within an airplane hanger.
Does anyone have any experience/recommendations on how to model the heat stratification within the building space using eQuest?
Apologies if this is a repeat question.
Thanks
