Godunov-type solutions for water hammer flows

WebWater hammer flows are almost simulated by using the Eulerian mesh methods including the most popular method of characteristics (MOC). In this paper, smoothed particle hydrodynamics (SPH) of the Lagrangian meshless method are introduced to simulate transient pipe flow considering the unsteady friction model (UFM). WebNov 1, 2016 · A second-order explicit Finite Volume Method (FVM) based on Godunov-type schemes is presented and applied to Water Column Separation (WCS) in pipelines.
