Abstract:
The motions of buoyant flows contained within vertical
shafts are being investigated in an experimental program
that will lead to a prediction of the transport of heat
and toxic materials within shafts due to buoyancy
controlled mixing and the stack effect when the
influence of heat transfer to the walls of the shaft can
not be neglected. This work is based in part on the
earlier experiments of Cannon, J. B. and Zukoski, E. E.
In this program, the basic flow under investigation is
the motion of hot air within a vertical shaft and the
subsequent heat transfer when the shaft is completely
closed except at the bottom.
