Abstract
There are several different methods to solve the steady-state flow problem of district heating networks and gas networks. In this thesis, the nodal method, the loop method, and the loop-node method are compared. This is done in order to determine for what type of network, with specific characteristics, which of these methods is preferred. In this comparison, the focus is on computer storage, sensibility to starting values, convergence properties, and computational time.
