Numerical Recovery of Gas Flows at Pipeline Accidents / Numeryczne Odtworzenie Warto?ci Przep?ywów Gazu W Przypadku Awarii Ruroci?gów

摘要

The article describes numerical method of physical gas flow parameters recovery at accidents investigation, which are conditioned by guillotine rupture of a pipe in gas trunkline and distribution pipeline systems. The information about full-scale measurements of time dependences of gas flow parameters at defined points inside pipelines system and at its boundaries is the base for recovery implementation at numerical investigation of accidents. Numerical recovery is carried out by defining and solving a special identification problem
