Reduced order modeling of fluid flows using convolutional neural networks
Journal of Fluid Science and Technology, 2023 Application of machine learning is currently one of the hottest topics in the fluid mechanics field. While machine learning seems to have a great possibility, its limitations should also be clarified.

Scientific challenges to characterizing the wind resource in the marine atmospheric boundary layer [PDF]
Wind Energy Science, 2022 With the increasing level of offshore wind energy investment, it is correspondingly important to be able to accurately characterize the wind resource in terms of energy potential as well as operating conditions affecting wind plant performance ...

Well-to-wake analysis of ethanol-to-jet and sugar-to-jet pathways [PDF]
Biotechnology for Biofuels, 2017 To reduce the environmental impacts of the aviation sector as air traffic grows steadily, the aviation industry has paid increasing attention to bio-based alternative jet fuels (AJFs), which may provide lower life-cycle petroleum consumption and greenhouse gas (GHG) emissions than petroleum jet fuel.

Imaging the jet-induced medium response with energy correlators [PDF]
EPJ Web of ConferencesQuark-gluon plasma (QGP), when viewed at length scales of order the inverse of its temperature, behaves as a strongly-coupled liquid. However, when it is probed with sufficiently high momentum transfer, asymptotic freedom mandates the presence of quark ...

Mixing and Isosurface Geometry in Turbulent Transverse Jets [PDF]
, 2001 Mixing and the geometry of jet-fluid-concentration level sets in turbulent transverse jets were experimentally studied. Jet-fluid concentration fields were measured with laser-induced fluorescence and digital imaging techniques for Reynolds numbers ...

Flow through a hexagonal mixing grid with parabolic vanes measured experimentally by PIV in two planes at distances 1 and 5 × the maximum inscribed diameter D at Reynolds number based on D of 1.5⋅104, 3.1⋅104 and 6.2⋅104 [PDF]
MATEC Web of ConferencesParticle Image Velocimetry (PIV) method is used to measure the flow through a prototype mixing grid for nuclear reactor. In this preliminary experiment, there are no fuel rods, the grid is empty.

Coastal impacts on offshore wind farms – a review focussing on the German Bight area
Meteorologische Zeitschrift, 2022 The atmospheric boundary layer experiences multiple changes in coastal regions, especially with wind directions from land towards the sea, where the wind speed usually increases due to the smaller roughness of the ocean surface.
