چکیده:

In this paper a general algorithm for modelling flow in open and closed conduits is presented. The two models (for the free-surface flow and for the pressurized flow) are written in single formulation by introducing a common set of variables and solved utilizing Time Splitting Projection Method (TSPM). Then Double Sweep Method is implemented to model flow in pipe and river networks. The proposed model is validated by comparing the numerical results with some benchmark analytical examples. Comparisons prove the efficiency of the model for simulating flow in both open and closed conduits without using higher order accurate techniques
