Abstract
The behavior of the pressure wave in a closed channel with a gas-liquid mixture is investigated. In the channel can be implemented corks with the different gas content. The structure of the slug flow is quasiperiodic. The transcendental dispersion equation is derived. The cell Bloch number dependence on a local wave numbers in the corks is derived. As illustration the water–air mixture is considered. Closing value of frequencies decreasing with increasing gas in corks, increasing with initial pressure magnification decreasing with increase of bubble sizes for high and ultrahigh forcing frequencies and are not changed for a low frequencies. As well as they decreasing when we take into account the dispersion effects in mixtures.
