Flow-pressure analysis of loop gas networksKrope, Jurij (Avtor) Trop, Peter (Avtor) Goričanec, Darko (Avtor) fluid mechanicsgas pipe networkslinear methodnon-linear programmingpressure lossesThis paper proposes a mathematical model underlying a computer program for flow-pressure analysis of loop gas pipe networks. The method is used on a test case with four nodes. The HAPN application for flow-pressure analyses of low pressure gas pipe networks is completely designed in object-oriented programming technology. The equations, which describe the physical flow-pressure conditions through every cross point are assumed to be continuous and the energy of every closed loop of analyzed network conserved. The system of non-linear equations was linearized by LTM (Linear Theory Method). The algorithm for numerical module LTM and the method for solution of sparse matrix are developed at the Faculty of Chemistry and Chemical Engineering, University of Maribor, Slovenia.20112012-06-01 08:21:12Neznano26830UDK: 532COBISS_ID: 15154198ISSN pri članku: 2074-1308NUK URN: URN:SI:UM:DK:KVH5GRYGsl
