Description: This paper presents a study of the phenomenon and the development of a computational code for water hammer with column separation and fluid-structure interaction (FSI) in one-dimensional. FSI model was considered as an initial and boundary value problem, represented by a system of hyperbolic partial differential equations that simultaneously describes the propagation of pressure waves in the liquid and axial stress waves in the structure. Column separation is treated as a boundary condition. Method of characteristics, combined with linear interpolations, was used to solve the system of hyperbolic partial differential equations. The proposed numerical model was compared to experimental data from the base article (BERGANT, ANTON et al., 2005) provided by author, for a system consisting of a reservoir with a constant upstream level, a single straight pipe and a downstream valve with rigid fixation.
