    The paper aims to investigate the dispersion law and mechanism of total iron from dead-end metal branch pipe to main pipe under the impact of hydraulic disturbance. A full-scale experimental water distribution network including a transport main pipe as well as six dead-end branch was set up and computational-fluid-dynamics (CFD) simulation are adopted to study the dispersion phenomenon. The cavity flow theory is adopted to clarify the inner dispersion mechanism. Firstly, the CFD model is examined through the comparison of results between the two experimental methods
    under the same condition. Secondly, performing the effect of the Reynolds number in main pipe on the total dispersion concentration of iron. Thirdly, the characteristics of interaction between flow field and the inner mechanism linked to streamline map and concentration distribution map are analysed based on the concept of cavity flow. The future research content is briefly proposed.
