Abstract :
Because of the growth rings within the water pipeline, a great impact on the health status of the pipeline and water pipeline transmission and distribution capacity, seeking practical ways to remove the growth rings are very meaningful. In this paper, pressure pulse method is applied for pipe cleaning test, analysis of experimental pipeline pressure and flow changes. Based on numerical simulation method, the unsteady air-water two-phase flow model is established to analyze two-phase flow changes in the pipeline, pressure and flow velocity fields and the nozzle outflow process.
