【Abstract】 For calculation of flow network in process simulation, the topology structure for flow network was described as an adjacency matrix and the strategy to identify flow network was studied with four sorts-series, parallel, branch and mixing, to put forward the algorithm for auto modeling and calculation of flow and pressure. It is shown that after the adjacency matrix of flow network is input, the algorithm can be employed to generate the model of flow network automatically and the practice with this method is successful.更多还原
