Impact of Pipe Leakage Location on Siphon Flow Breakage
Publication: World Environmental and Water Resources Congress 2022
ABSTRACT
Siphons are often used for releasing water by gravity, especially from shallow ponds. This paper investigates the hydrodynamic characteristics of the flow in a siphon under leakage (e.g., pipe puncture) and no-leakage conditions using the OpenFOAM Computational Fluid Dynamics (CFD) package. The volume-of-fluid (VOF) method was used to solve the air-water two-phase flow, and the standard k-ε model was used to model the turbulence. The CFD model was assessed using experimental measurements for the no-leakage condition. The simulations for the leakage condition focused on investigating the siphon flow break phenomenon as a function of leakage location. The results show the impact of leak position on the siphon flow break and the suitability of OpenFOAM for simulating the complex two-phase flow dynamics that occurs in a siphon.
