Minisymposium: Simulation and Optimization of Water and Gas Networks

Abstract

The minisymposium dealt with topics regarding aspects of modelling, simulating and optimizing flow behaviour within water and gas networks. These networks can consist of rivers or channels, gas and water supply or sewer systems. The flow in every single network element is usually modelled by hyperbolic conservation laws or some simplifications. In addition, single flow reaches given must be coupled by appropriate coupling and boundary conditions. This approach finally leads to PDAEs (partial differential algebraic equations) and requires very robust and efficient numerical methods for their solution. Moreover, the optimization of the network operation with respect to the security of supply or energy consumption is of importance. Suitable optimization methods for these requirements are an active field of research.
