Calculation of hydraulic transients in a complicated pumping system |
|
| Abstract: | The calculation method for the simulation of pressurized and free flows in complicated pumping systems is investigated. A unified scheme of characteristics is utilized to deal with the problem of free|surface|pressurized flows in the conduits during transient|state conditions. By the use of the model, the hydraulic transients in a large|scale complicated pumping system, which is composed of pumps, pipes, canals and ponds, have been carried out. |
| Keywords: | pumping station complicated pumping system free-surface-pressurized flow hydraulic transients |
