ABSTRACT:A chimney model for the Galaxy is presented and its underlying physical
principles are explained.
The crucial point of the model is that the Galactic disk
and halo are connected by chimneys which are a consequence of superbubbles
bursting out of the disk forming these collimated structures through which the
global mass and energy exchange flows from disk to halo.
For canonical Galaxy
parameters, the chimney phase is found to be associated with a mass flow rate of 0.3-3
solar masses/yr and a global power input of 10 to the 40th to 10 to the 42nd
ergs/s.
