On the Existence of Steady States for Blended Gas Flow with Non-Constant Compressibility Factor on Networks
Simone Göttlich, Michael Schuster, Alena Ulke
In this paper, we study hydrogen-natural gas mixtures transported through pipeline networks. The flow is modeled by the isothermal Euler equations with a pressure law involving a n…

Steady State Blended Gas Flow on Networks: Existence and Uniqueness of Solutions
Alena Ulke, Michael Schuster, Simone Göttlich
We prove an existence result for the steady state flow of gas mixtures on networks. The basis of the model are the physical principles of the isothermal Euler equation, coupling co…
