Classical transient pipe flow analysis with SPH method

Resumo

The main purpose of this paper is to analyze the applicability of the Smoothed Particle Hydrodynamics
(SPH) method in water hammer modeling, a transient pipe flow problem. A reservoir-pipe-valve system with
steady friction losses was chosen to implement the method. In order to suppress the limitations of the method due
to boundary conditions and numerical instability, numerical corrections were applied to the SPH. The applied
corrections are found in the kernel function (CSPH) and in the use of artificial viscosity. Furthermore, the method
is validated by comparing the numerical results obtained with SPH and the numerical solution obtained by the
Method of Characteristics (MOC).
