Safety assessment of buried pressurized gas pipelines subject to blasting vibrations induced by metro foundation pit excavation

Stability analysis of composite thin-walled pipes conveying fluid

Pipeline networks for gas transportation often contain circles.
For such networks it is more difficult to
determine the stationary states
than for networks without circles.
We present a method that allows to compute
the stationary states for subsonic pipe flow governed by
the isothermal Euler equations for certain pipeline networks
that contain circles.
We also show that suitably chosen boundary data
determine the stationary states uniquely.
The construction is based upon novel explicit representations
of the stationary states on single pipes
for the cases with zero slope and with nonzero slope.

In the case with zero slope,
the state can be represented using the Lambert--W function.
