Numerical Modelling of Water Hammer Using Differential Quadrature Method

In this research, Incremental Differential Quadrature Method (IDQM) is applied for modelling of unsteady flow (water hammer) in pipeline systems. This is considered as the first application of differential quadrature in this area. The implementation of the IDQM to the governing equations along with some numerical studies are presented. The main attractive feature of the proposed method compared with existing numerical techniques is unconditional stability.
