A very important flow and transport circumstance that
arises in enclosure fires is that of heat and mass
transfer across a horizontal vent. Such vents exist in
enclosed regions such as rooms and energy storage and
ventilation systems. It is important to understand the
basic nature of the transport processes which arise due
to density and pressure differences across such vents.
These two mechanisms give rise to very complicated flow
patterns, depending on the relative magnitude of each.
This paper represents the second phase of an on-going
experimental study on the flow of air across a
horizontal vent in an enclosed region for arbitrary
values of the governing variables and L/D, where L and D
are the length and diameter of the vent respectively.
The objective is to accurately quantify some of the
results obtained from an earlier visualization study.
