Adiabatic approach for natural gas pipeline computations [PDF]
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017 We consider slowly evolving, i.e. ADIABATIC, operational regime within a transmission level (continental scale) natural gas pipeline system. This allows us to introduce a set of nodal equations of reduced complexity describing gas transients in injection/consumption UNBALANCED (so-called line-pack) cases.
