The VORSEA Wind Tunnel Experiments

Abstract When preparing the installation of offshore wind turbines, the towers (cylindrical masts of large height supporting the hub and rotating blades) are first stored on harbor quayside and then moved on a special vessel for on-site installation.

Visualization of Flow Field: Application of PLIF Technique

Journal of Spectroscopy, 2018
The objective of this paper is to apply planar laser-induced fluorescence (PLIF) technology to flow field visualization. This experiment was carried out in a one-meter wind tunnel to study the wake flow field around a circular cylinder.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Prediction of unsteady blade loads of a wind turbine using RANS and vorticity transport methodologies

, 2010
Numerical simulations of the NREL phase VI wind turbine operating in yawed conditions have been performed using two computational methods; one based on the solution of the Reynolds-averaged Navier-Stokes equations (RANS) using unstructured overset meshes

The Wind-tunnel Test and Unsteady CFD of an Ornithopter Formation

, 2017
According to Lissaman and Shollenberger’s article published in Science in 1970, birds fly in formation to reduce the overall energy expenditure for flight. Thus, this work adopted the same principle of flight formation to ornithopters to save energy. Two
