Hydraulic transient analysis with the Smoothed Particle Hydrodynamics method coupled with unsteady friction model

This study uses the Smoothed Particle Hydrodynamics (SPH) method to analyze hydraulic transient phenomena in pipes. The Corrected SPH (CSPH) technique is used to rectify domain support boundary imbalances, and artificial viscosity is used to mitigate spurious oscillations. A comprehensive evaluation of unsteady friction models highlights the accuracy of the model proposed by Ramos (2004). The study optimizes critical parameters for minimal error between numerical and experimental results. The study reveals the impact of coefficients Kx and Kt on the accuracy of simulation responses. Additionally, the study emphasizes Δx and particle count for enhanced accuracy and stability. The proposed methodology demonstrates promising results in simulating hydraulic transients, contributing valuable insights for accurately modeling fluid flow phenomena.
