| A numerical model to analyze the unsteady flow in water distribution system was developed by using wave adjustment method. When analyzing the unsteady flow in the real water distribution system, the computational procedures are very complex due to the various boundary condition. Wave adjustment method, which can solve the boundary condition more simply and accurately, was introduced to overcome this difficulty and related equations to solve external flow directly were presented. Using these equations, the numerical model was developed to analyze water hammer. The suggested model was applied to a hypothetical distribution system and a real system with 26 pipes with various external flow boundary condition to evaluate the applicability of the developed model. The simulation results by this model agree with those by Karney's analysis in terms of discharge and pressure. |
