Research Interests

  • Industrial Two-Phase Flows
    In high-velocity turbulent flows, air bubbles are entrained at the free surface. This process (self-aeration) is caused by the turbulent velocity fluctuations acting next to the free surfaces. The presence of air within the flow increases the bulk of the flow, modifies the momentum shear layers and enhances the air-water gas transfer. The project is based upon new experimental investigations using large-scale experiments. The results enable a better understanding of the fluid mechanics of free-surface air-water flows.
  • Estuarine processes
    Investigation of the hydrodynamics and turbulent mixing in estuarine zones, under micro- and macro-tidal conditions. Field works. Computational Fluid Dynamics (CFD), Physical modelling.
  • Mixing and dispersion in rivers and estuaries
    Turbulent mixing in small estuaries with application to water quality modeling
  • Engineering heritage
    History of technology. Historical development of hydraulic engineering and structures, includings dams, spillways, weirs, culverts ...
  • Non-Newtonian fluid dynamics
    Experimental and theoretical study of non-Newtonian fluid flows, including thixotropic fluid flows, dam break, debris flows.
  • Open Channel Flow and Hydraulic Engineering
    Open channel flows are encountered in a wide range of applications from large rivers to roof gutters including irrigation channels. New research investigations include the hydraulic jump flows, undular flows, weir overflow, stepped cascades and supercritical flows. Applications to hydraulic structures cover high-head spillways, stepped chutes, rubber dams, stilling basins and water quality prediction.
  • Hydraulic structures
    Design and operation of spillway systems, incl. high head structures, large dams and overflow sections.
  • Air entrainment in hydraulic structures and industrial applications
    Study of air entrainment and air-water flows in hydraulics structures, hydraulic systems, re-aeration plants and water treatment systems.
  • Tidal bores
    A tidal bore is a surge of water propagating upstream in an estuarine zone when the tidal flow turns to rising and rushes into a funnel shaped river mouth with shallow waters. The bore forms typically during the early flood tide when the tidal range exceeds 4-6 m and the estuary bathymetry amplifies the tidal range with a low freshwater level. Worldwide it is believed that over 450 estuaries are affected by a tidal bore, on all continents except Antarctica. The interactions between tidal bores and mankind are complex. Tidal bores can be dangerous, impacting adversely on man-made structures and endangering lives. They can be also a major touristic and sport attraction. The aim of this research is to characterise the turbulent properties of bore fronts including the coupling between free-surface and velocity fluctuations, and impacts on sedimentary processes and ecology.

  • In recent years, the design floods of a number of dams were re-evaluated and the revised flows were often larger than those used for the original designs. In many cases, occurrence of the revised design floods would result in dam overtopping because of the insufficient storage and spillway capacity of the existing reservoir. A number of overtopping protection systems were developed for embankments and earthfill dams. These include concrete overtopping protection systems, timber cribs, sheet-piles, riprap and gabions, reinforced earth, Minimum Energy Loss weirs, and the precast concrete block protection systems developed by the Russian engineers (http://www.uq.edu.au/~e2hchans/over_st.html). Recent studies demonstrated a strong correlation between air entrainment, stepped chute hydrodynamics and turbulence. The findings imply that the rate of energy dissipation on stepped spillways might be drastically affected by the interactions between entrained air and flow turbulence.

  • When a river mouth has a flat, converging shape and when the tidal range exceeds 6 to 9 m, the river may experience a tidal bore (http://www.uq.edu.au/~e2hchans/tid_bore.html). A tidal bore is basically a series of waves propagating upstream as the tidal flow turns to rising. It is a positive surge. As the surge progresses inland, the river flow is reversed behind it. The best historically documented tidal bores are probably those of the Seine river (France) and Qiantang river (China). The mascaret of the Seine river was documented first during the 7th and 9th centuries AD, and in writings from the 11th to 16th centuries (http://www.uq.edu.au/%7Ee2hchans/mascaret.html). It was locally known as "la Barre". The Qiantang river bore, also called Hangzhou bore, was early mentioned during the 7th and 2nd centuries BC, and it was described in 8th century writings. The bore was then known as "The Old Faithful" because it kept time better than clocks. A tidal bore on the Indus river might have wiped out the fleet of Alexander the Great. Another famous tidal bore is the "pororoca" of the Amazon river observed by Pinzon and La Condamine in the 16th and 18th centuries respectively. The Hoogly (or Hooghly) bore on the Gange was documented in 19th century shipping reports. Smaller tidal bores occur on the Severn river near Gloucester, England, on the Garonne and Dordogne rivers, France, at Turnagain Arm and Knik Arm, Cook Inlet (Alaska), in the Bay of Fundy (at Petitcodiac and Truro), on the Styx and Daly rivers (Australia), and at Batang Lupar (Malaysia). In the present study, physical modelling will be used to reprodduced full-scale observations and to gain new insights in the unsteady hydrodynaics. The results will provide some new understanding of mixing processes in tidal-bore-affected estuaries.

  • In water supply channels, the brusque operation of control gates may induce large unsteady flow motion called surges. Such a rapid operation of gates must often be restricted, although it may be conducted to scour silted channels and sewers. Herein a physical study will be conducted under controlled flow conditions to study the turbulent mixing in the very-close vicinity of a rapidly opening/closing gate, with a focus on the unsteady transient mixing induced by the gate operation. The processes are associated with large Reynolds stress levels. A succession of rapid closure and opening of undershoot gates may provide optimum conditions to scour silted canals, and the present study will provide some detailed insights into the physical processes.

  • Man-made instream structures (e.g. dams and road crossings) have contributed to major declines in native fish numbers, with > 6,000 barriers to fish migration occurring in NSW alone. Recognising this, this project will integrate data on the swimming ability of Australian fish species with culvert hydraulic modelling to better understand fish requirements in and around road crossings. These data will strengthen national design guidelines and provide the tools engineers and planners need to balance fish migration with effective water management.

    This project will provide data on the ability of Australian fish to successfully ascend through road crossings (culverts). These data will be used to develop National recommendations for ‘fish-friendly’ road crossing designs which better integrate the requirements of native fish with the need for cost-effective water management around roads.

  • In an open channel, the transformation from a supercritical flow into a subcritical flow is a rapidly varied flow with large turbulent fluctuations, intense air entrainment, and substantial energy dissipation called a hydraulic jump. New experiments will be conducted to quantify its fluctuating characteristics in terms of free-surface and two-phase flow properties for a wide range of Froude numbers at relatively large Reynolds numbers. Although te time-averaged free-surface profile presents a self-similar profile, the longitudinal movements of the jump will be documented, for both fast and very slow fluctuations for all Froude numbers. The air–water flow measurements will quantify the intense aeration of the roller and the strong interactions between the jump roller turbulence and free-surface fluctuations.

  • In recent years, the design floods of a number of dams were re-evaluated and the revised flows were often larger than those used for the original designs. In many cases, occurrence of the revised design floods would result in dam overtopping because of the insufficient storage and spillway capacity of the existing reservoir. A number of overtopping protection systems were developed for embankments and earthfill dams. These include concrete overtopping protection systems , timber cribs, sheet-piles, riprap and gabions, reinforced earth, Minimum Energy Loss weirs, and the precast concrete block protection systems developed by the Russian engineers. New physical tests will be a conducted ina a large-size facility to optiise present design guidelines.

  • Plunging jet flows are employed to produce some gas-liquid interface, typically to dissolve gas in liquid. They are bottlenecks in minerals and food processing, biotechnology and waste-water treatment. The mechanisms of air bubble entrainment by circular plunging jets will be investigated in the light of new experimental evidence. The results will be obtained in the developing flow region. While void fraction distributions follow closely an advective diffusion theory, the bubble count rate distribution exhibit consistently a maximum in the inner side of the void fraction peak indicating some bubble-turbulence coupling. Both intrusice phase-detection probe measurements and high-speed video imaging of the bubbly flow will be conducted with void fractions up to 40%.

  • When a river mouth has a flat, converging shape and when the tidal range exceeds 6 to 9 m, the river may experience a tidal bore {http://www.uq.edu.au/~e2hchans/tid_bore.html}. A tidal bore is basically a series of waves propagating upstream as the tidal flow turns to rising. It is a positive surge. As the surge progresses inland, the river flow is reversed behind it. New research into the unsteady hydrodynamics of tidal bores and postive surges will be investigated ina large-size physical model. This study aims to characterise the impact of tidal bores on the turbulent dispersion of fish eggs and on water quality.

  • Flood waves resulting from dam breaks and flash floods have been responsible for numerous losses. In the present study, sudden flood releases were investigated down a initially dry waterway, while additional tests may be conducted on an initially filled waterway. oth Newtonian and non-Newtonian fluid flows may be considered.

  • Dispersion of matter in natural river systems is of considerable importance, particularly in relation to the transport of nutrients, sediment and toxicants into ecosystems as a result of stormwater runoff and wastewater discharges. The project aims to improve our basic understanding of turbulent mixing and the influence of anthropogenic releases in small subtropical estuaries, and to develop improved predictive models to assist with the management and monitoring of natural ecosystems. This will be achieved through a Ph.D. research project integrating basic water engineering and environmental sciences. The project is part of an active cross-institutional multidisciplinary research effort.
