Unsteady simulation of natural gas networks [PDF]

open access: yesAIP Conference Proceedings, 2019
Gas networks work with time-dependent flow demand and sometimes in emergency conditions or the presence of undesired situations. In this scenario, unsteady simulations are necessary to design, control and analyze gas network systems. The Gas Network Solver, developed by the authors, aims to simulate the behavior of gas transportation pipelines with ...
