Finite-difference-based simulation and adjoint optimization of gas networks
Sonja Hossbach, Mathias Lemke, Julius Reiss
The stable operation of gas networks is an important optimization target. While for this task commonly finite volume methods are used, we introduce a new finite difference approach…
