Based on theoretical analysis of aerodynamic characteristics in the discharge siphon flow passage, transient electric and dynamic characteristics of pump setting, the mathematical calculation model of transient parameters during starting period is put forward considering unsteady flow, pump performance curve and similitude laws in low-head siphon pumping installation.

Optimim design for siphon outlet of liulaojian No.2 pumping station;

A new operating way of quick-stop gate for drainage pumping station with siphon outlet;

Optimum hydraulic design for siphon outlet in large pumping stations;

Numerical computation of interior flow and hydraulic design optimization for siphon outlet conduit;

Numerical computation of the three-dimensional turbulent flow in siphon outlet conduit of large pumping stations;

Combined with the study of integer hydraulic model test of pumping stations in Shanghai to get water from the Yangtse River,a measure aiming at improving the characteristic of siphon outlet conduit with a long and straight conduit after the roof which is difficult to form siphon is put forward in this paper.

The complexly designed geometry of siphon outlet passages which are widely used in large pumping stations,gives rise to uneven flow distribution in the passages,even some problems,for instance,swirl,reflux and flow separation.
