Convective heat and mass transfer through large openings play an impor
tant role in the thermal behaviour of buildings. These phenomena becom
e even more determinant in the case of naturally ventilated buildings.
This paper reviews the models describing the involved phenomena due t
o gravitational and boundary layer pumping flows proposed up to 1992.
A sensitivity analysis is also presented, aimed at a comparison of the
se models and a determination of the points requiring further research
.
