Abstract

An efficient quasi-2D numerical waterhammer model for turbulent waterhammer flows has previously been developed for a single pipe system (reservoir-pipe-valve system). Basic boundary conditions, such as valves, reservoirs, and external flows, were also implemented. This paper extends this previously developed efficient scheme to a general model for multi-pipe system. More precisely, an approach for matching the family of characteristics equations in each pipe at a junction of two or more pipes is proposed. The resulting model is applied to two system involving pipes in series and another system involving a pipe network. From the case studies, it is found that the quasi-2D model is highly efficient, robust and suitable for application to waterhammer problems in real complex pipe system.
