| Abstract: | This paper emphasizes on the investigations of numerical simulation of water hammer in single-phase flow in order to describe precisely the process that the pressure wave propagates and the interaction with system boundaries.Depending on their physical characteristics, the author establishes arithmetic models and chooses the suitable numerical method to write single phase water hammer analysis programs.For single-phase water hammer,we use the conventional numerical method and constructs the arithmetic models of piping components.From benchmark cases,it is known that the MOC method can precisely describe the pressure wave propagation process. |
