Construction of a Mathematical Model of the Flow Characteristics of a Multiphase Pipeline with Regard for the Phase Transitions in It.

A simulation of the flow of a gas–liquid medium in a multiphase pipeline has been performed for the purpose of diagnostics of its flow characteristics. It was established that, in the case of flow of a gas–liquid medium with phase transitions in such a pipeline, its flow characteristics can be unstable, and this instability manifests itself as a local decrease in the pressure loss in the pipeline.
