Consideration has been given to liquid flows in a simple pipeline and in an intricate branched pipeline system with local hydraulic resistances in the presence of gas release to form a fine-bubble two-phase suspension. On the basis of a numerical method of characteristics, the authors have proposed an algorithm for calculation of such flows. Peculiarities of transient hydrodynamic processes have been established which are due to the effects of gas release on the startup of the system and it reaching a stationary regime of flow. With the example of feed lines of a system of bipropellant low-thrust control rocket engines, the influence of gas release on the system′s operation in a pulsed regime has been shown.
