Applications of optical flow technique in air-water flows [PDF]
Australasian Fluid Mechanics Conference (AFMC), 2020 In air-water flows, the presence of bubbles hinders the application of traditional velocimetry techniques, such as particle image velocimetry, acoustic Doppler velocimetry and laser Doppler velocimetry, etc. Image-based velocimetry recently received much attention, particularly the optical flow (OF) technique, which detects the apparent motion between ...

Horizontal air-water flow pattern recognition [PDF]
WIT Transactions on Engineering Sciences, 2013 A Wire Mesh Sensor (WMS), based on the measurement of the local instantaneous conductivity of the two-phase mixture, has been adopted to characterize the air-water flow in a test section consisting of a horizontal Plexiglas (transparent) pipe of internal diameter 19.5 mm and total length of about 6 m.

Experimental evaluation of ISA 1932 nozzle for differential pressure measurement in air–water two-phase flows [PDF]
EPJ Web of ConferencesAccurate measurement of multiphase flows remains a significant challenge because of complex phase interactions and flow-regime variability. This study investigates the use of an ISA 1932 nozzle for differential pressure-based measurement of air–water two-

Air-water countercurrent annular flow
International Journal of Multiphase Flow, 1979 Abstract Experimental results on investigation of countercurrent air-water flows in vertical circular tubes of a range of diameters are reported. Based on the influence of tube end geometries on measured countercurrent fluxes, liquid fraction, and pressure gradients, analogies between countercurrent gas-liquid flow and other more familiar flows in ...

Lower nappe aeration in smooth channels: experimental data and numerical simulation
Anais da Academia Brasileira de Ciências, 2010 Bed aerators designed to increase air void ratio are used to prevent cavitation and related damages in spillways. Air entrained in spillway discharges also increases the dissolved oxygen concentration of the water, which can be important for the ...

Image-based measurements of air-water flow properties in plunging air-water jets [PDF]
Proceedings of the 8th IAHR International Symposium on Hydraulic Structures ISHS2020, 2020 A high-speed water jet plunging into a slower receiving waterbody results in an air entrainment process. In hydraulic engineering, a plunging jet is commonly used as an energy dissipater downstream of a hydraulic structure, such as stepped chute flow and water treatment plants.
