Optimization of gas pipelines simulation determines the optimum conditions within the network by a simplified representation of the real-world conditions of a gas network. Optimization aims to determine the flow capacity of the pipeline, the optimum gas properties, or the minimum cost of operations. This book looks at optimizing the gas flow and pressure along the pipes and junctions between pipes (nodes), given initial parameters of demand or load and pressure at the sources for the network. The networks were modelled with the flow equations, simplified with matrix representation, and solved...
