Safe operation of inverted siphon during ice period
Journal of Hydrodynamics, 2015Abstract Sixteen inverted siphons are in operation at the Beijing-Shijiazhuang section in the Middle Route of the South-to-North Water Diversion Project. Their safe operation is closely related to the safety and the water diversion efficiency of the whole project during an ice period.

Preventing Sediment Deposition in Inverted Sewer Siphons
Journal of Hydraulic Engineering, 2003Laboratory experiments were carried out to determine minimum self-cleansing velocities for preventing deposition of sediment in upward sloping and vertical pipes of inverted siphons. Tests were made using sediment sizes of 0.78 and 4.3 mm in a pipe of 150 mm diameter for eight angles of inclination between 0 and 90°.

A simplified approach for the computation of steady two-phase flow in inverted siphons
Journal of Environmental Management, 2016Hydraulic, sanitary, and sulfide control conditions of inverted siphons, particularly in large wastewater systems, can be substantially improved by continuous air injection in the base of the inclined rising branch. This paper presents a simplified approach that was developed for the two-phase flow of the rising branch using the energy equation for a ...

Pipe Culverts – Throttling Pipes – Inverted Siphons
2010Culverts are characterized hydraulically by various flow conditions. They are discussed first and then analyzed with a generalized diagram to present a simple design method. The so-called simple culvert is also considered, and the computational approach is compared with model tests.

Minimum Self-Cleansing Velocities for Inverted Sewer Siphons
Building Partnerships, 2000Laboratory experiments were carried out to determine minimum self-cleansing velocities for preventing deposition of sediment in upward sloping and vertical pipes of inverted siphons. Tests were made using sediment sizes of 0.78mm and 4.3mm in a pipe of 150mm diameter for eight angles of inclination between 0° and 90°.

Experimental Investigations of Sedimentation at an Ascending Inverted Siphon Branch
Volume 2: Multiphase Flows Applications; Fluids Applications; Microfluidics; Fluids Mechanics Fundamentals; Fluids Engineering EducationAbstract The reliable transport of wastewater in both urban and rural areas faces a variety of challenges. One of the key difficulties is bypassing obstacles such as rivers, canals, and subway lines. Particular designs of culverts, so-called Inverted Siphons, are well-suited to circumvent these critical locations.

Self-Vibration Characteristics of Plane Gate in Inverted Siphon Project
Applied Mechanics and Materials, 2012Based on the vibration problem of the plane gate in the inverted siphon exit of a large-scale hydraulic project in northern Xinjiang, the software ANSYS is used to build the entity model and finite element model. Considering the influence of fluid-solid coupling, the self-vibration characteristics of the gate in the water and without water are analyzed.
