Study on the Effect of Air Injection Location on the Drag Reduction in SWATH with Air Lubrication
Journal of Marine Science and Engineering, 2023 In this paper, the air lubrication method is applied to high-speed SWATH (small waterplane area twin hull) to reduce the resistance. The influence of air injection locations on drag reduction is investigated.

Chemical characterization of submicron aerosol and particle growth events at a national background site (3295 m a.s.l.) on the Tibetan Plateau [PDF]
Atmospheric Chemistry and Physics, 2015 Atmospheric aerosols exert highly uncertain impacts on radiative forcing and also have detrimental effects on human health. While aerosol particles are widely characterized in megacities in China, aerosol composition, sources and particle growth in rural

Impact of Air Pressure in Subsoiling on Soil Permeability
Guan'gai paishui xuebao, 2023 【Objective】 The dense plough layer is difficult for airs and water to move into and out the root zone, hindering root penetration as a result. Deep loosening techniques, including the innovative air pressure subsoiling method, offer a solution by ...

Air Convection in the Active Layer of Rock Glaciers [PDF]
Frontiers in Earth Science, 2020 Coarse blocks are an abundant surface cover in mountainous permafrost landscapes. In this coarse blocky layer, air convection occurs and has a significant influence on the ground thermal regime of the underlying permafrost. Besides heat transfer through conduction, free convection of air takes place seasonally and leads to a pronounced ground cooling ...

Air/water turbulent boundary layer [PDF]
AIP Conference Proceedings, 2021 The paper presents the measurement results of the velocity vector and the Reynolds stress tensor profiles in a turbulent boundary layer at air-water interface, when the dynamic pressure of the gas flow is sufficient to induce the movement of the upper layers of the liquid with the generation of waves without drop entrainment.

Journal of Fluid Science and Technology, 2008 Recently, small hydropower attracts attention because of its clean, renewable and abundant energy resources to develop. Therefore, a cross-flow hydraulic turbine is proposed for small hydropower in this study because the turbine has relatively simple ...

Multi-method determination of the below-cloud wet scavenging coefficients of aerosols in Beijing, China [PDF]
Atmospheric Chemistry and Physics, 2019 Wet scavenging is one of the most efficient processes for removing aerosols from the atmosphere. This process is not well constrained in chemical transport models (CTMs) due to a paucity of localized parameterization regarding the below-cloud wet ...

Leaping shampoo glides on a lubricating air layer [PDF]
Physical Review E, 2013 When a stream of shampoo is fed onto a pool in one's hand, a jet can leap sideways or rebound from the liquid surface in an intriguing phenomenon known as the Kaye effect. Earlier studies have debated whether non-Newtonian effects are the underlying cause of this phenomenon, making the jet glide on top of a shear-thinning liquid layer, or whether an ...
