Experimental Study on Influence of Pitch Motion on the Wake of a Floating Wind Turbine Model
Energies, 2014 Wind tunnel experiments were performed, where the development of the wake of a model wind turbine was measured using stereo Particle Image Velocimetry to observe the influence of platform pitch motion.

Towards a Simplified DynamicWake Model Using POD Analysis
Energies, 2015 We apply a modified proper orthogonal decomposition (POD) to large eddy simulation data of a wind turbine wake in a turbulent atmospheric boundary layer. The turbine is modeled as an actuator disk.

Numerical investigation of wind turbine wakes under high thrust coefficient
Wind Energy, 2022 We study wind turbine wakes of rotors operating at high thrust coefficients (CT > 24/25) using large‐eddy simulations with a rotating actuator disk model. Wind turbine wakes at high thrust coefficients are different from wakes at low thrust coefficients.

The interaction between the Moon and the solar wind [PDF]
, 2011 We study the interaction between the Moon and the solar wind using a three-dimensional hybrid plasma solver. The proton fluxes and electromagnetical fields are presented for typical solar wind conditions with different magnetic field directions.

Vortical structure in the wake of a transverse jet [PDF]
, 1994 Structural features resulting from the interaction of a turbulent jet issuing transversely into a uniform stream are described with the help of flow visualization and hot-wire anemometry. Jet-to-crossflow velocity ratios from 2 to 10 were investigated at

Fluidic force and wake velocity of 3D body with four limbs in uniform flow
Journal of Fluid Science and Technology, 2023 Robots that operate at a disaster site have been proposed and the dispatch of rescue robots to such site is required. However, discussion on the transport of these robots is insufficient.

Wake flow visualization of a dandelion pappus with posture change
Journal of Fluid Science and Technology, 2023 A typical plant that is distributed by wind is the dandelion, which possesses a complex hairy pappus that aids in flying. A pappus or group of bristly filaments found in plumed seeds is believed to have a role in drag enhancement. The pappus prolongs the
