Abstract: As a key and indispensable component of urban fire protection systems, the design and operational quality of fire-fighting branch pipe networks exert a critical influence on fire prevention and control effectiveness. This study compares four branch pipe network layouts—central-terminal, central-center, side-terminal, and side-center—by adopting numerical simulation methods to systematically investigate water hammer effects and particle adhesion patterns at varying heights. The simulation results clearly show that symmetric layouts have obvious advantages over asymmetric ones: they outperform asymmetric layouts in dispersing water hammer pressure waves, reducing pressure peaks, and shortening stabilization time. Pipeline elevation shows no obvious correlation with pressure amplitude; however, increasing height will prolong stabilization time while reducing particle adhesion. This research quantifies the relationship between pipeline network layouts, water hammer effects, and particle erosion, thus providing a solid theoretical basis for optimizing fire-fighting pipeline network designs and formulating protection strategies. These findings further contribute to enhancing the safety and economy of fire protection systems.
