Transient mixed flow occurs under particular conditions in a closed conduit, in which both free-surface and pressurized flow come into existence simultaneously. Depending on the origin of the mixed flow, systems experiencing this phenomenon may encounter several problems. Successful simulation of mixed flows is, therefore, necessary to predict and overcome the problems encountered. Different methods are suggested for the simulation of the mixed flows. In this research, the transient mixed flow in closed conduits has been analyzed by the slot method. The capabilities of the proposed model are assessed by the results of a physical model and the results are presented. The model is further used for the prediction of a transient mixed flow in a real-word pipeline system. The results are then used for devising some operational guidelines.
