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.
