In two-phase flows, the interface at which the phases are in contact to one another is of high importance. One way to manipulate the dynamic of this interface is to modulate the pressure field within the gas phase. Accordingly, it is intended to study the influence of pressure modulation in a gas pipe with multiple openings. In this content, the system characteristics should be defined and the effect of individual parameters, which influence the temporal change of the pressure field at the openings are going to be studied. These parameters include frequency and amplitude of excitations, pressure fluctuation, geometry of the pipe and the openings, gas flow rate, etc. To peruse this idea, it is intended to simulate the gas pressure field in the pipe and under the opening using COMSOL Multiphysics.
