Research on Leakage Characteristics and Accurate Discharge Formula of Water Supply Pipeline
In this paper, based on the computational fluid dynamics method, the k-ε turbulence model is used to establish a steady state model to investigate the leakage law of the pipeline with a single leakage point. Starting from the three basic information of leakage port shape, leakage port area, and pipeline pressure, when the variables are changed, we investigate the change of the pressure flow field inside the leakage port and the influence on the leakage volumetric flow rate of the pipeline. Numerical simulation results show that: The shape of the leakage port, the internal pressure of the pipe, and the area of the leakage port all have influence on the pressure flow field inside the leakage port; the leakage coefficient is directly proportional to the area of the leakage port, which in turn introduces the leakage influence coefficient, and accurately optimizes the discharge formula to obtain the leakage loss formula of the pipeline under different leakage port shapes.
