Abstract: In oil-water two-phase dispersed flow, phase inversion may occur when the continuous phase becomes dispersed. This phenomenon, which controls the nature of the phase in contact with the pipe, ...

Abstract: Low-level outlets are essential flood discharge structures for high-head dams. High-speed free-surface flows releasing into tunnels lead to substantial air discharge, and the air supply is important for gate vibration ...

Abstract: Airport refueling systems, composed of parallel pumps and pipe networks, serve as critical infrastructure within the realm of civil aviation. Although the optimal scheduling of centrifugal pumps based on the steady state ...

Abstract: Worldwide, the pipeline mileage has increased dramatically since 1948 when the industry began to keep mileage statistics for pipeline construction, especially in China. Before operating long distance oil and gas pipelines, ...

Abstract: An air pocket is very likely to be trapped in a downward-sloping pipe (DSP) when water fills an undulating pipeline consisting of a series of inclined U-shaped pipes. To investigate the entrainment and evolution behavior ...

Abstract: The fundamental function of a natural gas pipeline network is to transport enough natural gas to users. Therefore, user characteristics should be considered in the formulation of the flow allocation plan of the pipeline ...

Abstract: The use of chemicals and abrasives for highway winter maintenance operations is an essential strategy for ensuring a reasonably high level of service, yet the performance of such materials has to be balanced with their ...

Abstract: Pigging technology is currently widely used in the oil and gas industry. The unstable movement of the pig in the pigging process after a water pressure test will not only affect the operation of pipes, but may even cause ...
