The Urban Unsteady and Non-Pressure Rain Pipe Flow Routing by the Dynamical-Wave Method

Abstract:

The dynamical-wave method routing model of the unsteady and non-pressure rain pipe flow was be established by conservation of mass, momentum and energy in the city unsteady and non-pressure rain pipe flow, and it was resoled by applying the four concealing style differences and the pursue method. Results by experiment checking computations and comparative analysis state that this routing model can reflect flood peak propagate in pipeline attenuate and backwater etc. influence, has high calculation precision, possess vast sphere of application, and can adapt to performing the city rain pipe flow routing in the distinct situation of the different incline degrees and enter runoff. This routing model supplies the scientific foundation to the town rainfall piping design or checking, administration of storm runoff, and so on.
