Effect of a wake on drag and deformation of liquid column at high Weber numbers
Journal of Fluid Science and Technology, 2020 The objective of this study is to clarify the effect of a wake on liquid column drag and deformation for a high-Weber-number (We) flow. A simulation was performed for a liquid column with a high We behind a shock wave, using a ghost fluid method as a two-

Wind farm power optimization through wake steering
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Wake effects within wind farms can significantly decrease the power production and increase the cost of electricity. Herein, we designed a wake steering control scheme to increase the power production of wind farms.

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

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 cool wake around 4C 34.16 as seen by XMM-Newton [PDF]
, 2005 We present XMM-Newton observations of the wake-radiogalaxy system 4C34.16, which shows a cool and dense wake trailing behind 4C34.16's host galaxy. A comparison with numerical simulations is enlightening, as they demonstrate that the wake is produced ...

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.
