INFLUENCE OF THE GAS SATURATION OF A LIQUID ON THE PECULIARITIES OF UNSTEADY FLOWS IN INTRICATE PIPELINES

Consideration has been given to liquid fl ows in a simple pipeline and in an intricate branched pipeline system with local hydraulic resistances in the presence of gas release to form a fi ne-bubble two-phase suspension. On the basis of a numerical method of characteristics, the authors have proposed an algorithm for calculation of such fl ows. 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 fl ow. With the example of feed lines of a system of bipropellant low-thrust control rocket engines, the infl uence of gas release on the system′s operation in a pulsed regime has been shown.
