Abstract
Experimental investigations on a physical model of a gallery performed in the
Laboratory of Structures Hydraulics at the University of Liege are presented. The
study focuses on the influence of the gallery aeration rate on the mixed flow
pattern and the pressure distribution. In particular, the effect of air vents on the
flow patterns and the release capacity of the gallery are assessed. An unusual
mechanism leading to a two-phase instability is also pointed out when the
aeration rate is not sufficient. Experimentations are completed with numerical
computations performed with an original 1D model developed by the authors to
give new insight into the mechanisms involved.
Keywords: hydraulics, mixed flows, civil engineering, aeration.
