| Abstract: | A numerical model of transient flow in pipe networks due to pump failures was developed in this paper, in which nonlinear dimensionless pump failure boundary conditions were considered. In addition inner boundary conditions for the pipes junctions were defined. The characteristic method was used to solve the differential equations. The model has been verified and the results showed that it was reliable and applicable in project design and analysis. The results of simulation indicated that the reverse flow was produced through the pump. Therefore some measures have to be taken to prevent it from occurring. After pump failure, the flow in the pipe network will finally reach another steady state. |
