MODELING AND NUMERICAL SOLUTION OF REAL LIQUID TRANSPORTATION PROCESSES IN PIPELINE SYSTEMS

The problems of transition from one stationary flow regime to another in a pipeline with a constant slope are considered. At the entrance to the section, the pressure value is set, and at the exit - the mass flow rate of the liquid .Modeling of the process of propagation of compaction and vacuum waves in an elementary section of a pipeline was carried out according to the linearized quasi- one-dimensional model of N.E. Zhukovsky.
