Simulation of compression waves/shock waves propagation in the branched pipeline systems with multi-valve operations

With the help of the developed model and numerical method the task has been solved concerning the transmission of the compressive wave complex in the branching pipeline system when several shut down valves operate. It is shown that for branches of the pipeline the highest peak of pressure can be achieved in them under the asynchronous operation of the shutdown valves, but not under the simultaneous operation of all valves, as it has been assumed in previous studies.
