Experimental and numerical model for analysis of the water hammer in pump water supply system

Abstract

Water supply systems in such transient regimes should be hydraulically analyzed by means of basic equations for unsteady flow. For the needs of this research, by using the method of characteristics, a custom mathematical model HTM is developed for the purpose of water supply network analysis in conditions of unsteady flow, i.e. with this mathematical model, the characteristics of the water hammer in closed systems for water transport under pressure can be seen. In addition, a physical model in ratio 1:1 has been made for in-situ analyses of pressure change in occurrence of water hammer in the water supply system.
