Abstract

The one-velocity motion of a gas–liquid
medium with a variable mass fraction of
the gas phase, which is equilibrium in
terms of phase pressures, is considered.
The existence conditions of nonlinear
periodic wave packets similar in
structure to roll waves in open inclined
channels are found. The structure of
travelling waves in the medium with
continuous addition of energy to the gas
phase is studied.
