Undesired flows in lateral-intake multiple forebays and their hydraulic implications: case study for Asia’s largest urban water supply pumping station

Autor: Jinghong Li, Jian Zhou, Hui Xu, Jiangang Feng, Hongwei Tong, Yaohui Chen, Shangtuo Qian

Publikováno v: Engineering Applications of Computational Fluid Mechanics, Vol 18, Iss 1 (2024)

Urban pumping stations often adopt the design of lateral-intake multiple forebays to accommodate multiple pump units in a limited space and to reduce interaction between the operating units. However, a full understanding of the undesired flows and hy

Joint effects of gas bubbles and solid particles on sonochemical inhibition in sonicated aqueous solutions

Autor: Kunpeng Su, Binghui Li, Jianhua Wu, Pei Xin, Shangtuo Qian

Publikováno v: Ultrasonics Sonochemistry, Vol 101, Iss , Pp 106717- (2023)

Wastewater is a multicomponent and multiphase mixture. Gas bubbles and solid particles in the dispersed phase influence sonochemical efficiency during ultrasonic treatment of wastewater, sometimes unfavorably; however, the influencing factors and mec

Standing waves of the stepped dropshaft in a deep tunnel stormwater system

Autor: Jingkang Sun, Shangtuo Qian, Hui Xu, Yaohui Chen, Weichen Ren

Publikováno v: Water Science and Technology, Vol 87, Iss 2, Pp 407-422 (2023)

The deep tunnel stormwater system, consisting of dropshafts and underground tunnels, is used to alleviate or prevent urban water problems associated with extreme rainfall events. The stepped dropshaft can transport surface runoff to the tunnels with

Hydraulic performance of helical-step dropshaft

Autor: Weichen Ren, Jianhua Wu, Fei Ma, Shangtuo Qian

Publikováno v: Water Science and Technology, Vol 84, Iss 4, Pp 954-965 (2021)

Aiming to achieve energy dissipation and prevention of cavitation erosion, a kind of dropshaft in urban drainage systems called the helical-step dropshaft is introduced in this paper. It dissipates flow energy by means of step geometry and prevents c

Three-dimensional numerical simulation of stepped dropshaft with different step shapes

Autor: Jingkang Sun, Shangtuo Qian, Hui Xu, Xiaosheng Wang, Jiangang Feng

Publikováno v: Water Supply, Vol 21, Iss 2, Pp 581-592 (2021)

The deep tunnel system is increasingly used worldwide for stormwater conveyance and storage, providing a robust and effective means of preventing urban waterlogging. In the system, the dropshaft, with the function of conveying stormwater to the deep

Effects of Converging Sidewalls on Skimming Flow over Converging Stepped Spillway

Autor: Yuling Chen, Guangyuan Liu, Shangtuo Qian, Hui Xu, Jiangang Feng, Xiaosheng Wang

Publikováno v: Applied Sciences, Vol 12, Iss 15, p 7868 (2022)

A numerical study is conducted for converging stepped spillways with various spillway slopes, sidewall convergence and flow discharges to understand the influences of converging sidewalls on skimming flows. Compared with the traditional uniform-width
