Project Title:
Air-water flows in urban drainage systems
Supervisor:CHAN Shu Ning
Co-Supervisor:-
Quota:2
Project Description:Air-water two-phase flows are commonly found in urban drainage systems. In steep spillways, aeration results in energy dissipation and reduces the possibility of cavitation damage to the spillway surface. In underground drainage tunnels, air may be entrapped, transported by the flow and released at vertical shafts/openings as violent geysers, causing damage to the drainage infrastructure and threaten the properties and pedestrians nearby. In addition, entrapped and dissolved poisonous foul gases may release from the sewage and sediments in underground sewers, endangering the safety of workers; fatal incidents have been reported worldwide from time to time. Air-water flows remain one of the most challenging fields in water and hydraulic engineering research. This project aims at developing new experimentation and mathematical modelling technology for better understanding of air-water flow mechanisms.
