A Boundary-Vorticity Perspective on Lift Enhancement at Ultra-Low Reynolds Numbers
Journal of Aerospace Sciences and Technologies, 2023 The ultra-low Reynolds number flow over airfoils is considered from the perspective of boundary vorticity dynamics in this paper. The dynamic balance between the streamwise pressure gradient and vorticity creation rate at the wall is highlighted by the ...

Lift Enhancement on Oscillating Airfoils [PDF]
39th AIAA Fluid Dynamics Conference, 2009 Force and particle image velocimetry measurements were conducted on a NACA 0012 airfoil undergoing sinusoidal plunge oscillations at amplitudes of 2.5% to 20% of chord, a post-stall angle of attack of 15°, and Reynolds number of 10,000. It was shown that airfoil oscillations significantly increase lift and reduce drag. Lift improvement is primarily due

Effects of Plasma Actuator Discharge on Lift-Enhancement and Flow Patterns of Flying Wing Aircraft [PDF]
Xibei Gongye Daxue Xuebao, 2018 The nanosecond pulsed plasma discharge actuator is used on a flying wing aircraft. At the angles of attack rang from -4° to 28°, the impact of plasma actuator arrangement position and discharge frequency on lift-enhancement effect is tested.

Facial Rejuvenation Enhancing Cheek Lift [PDF]
Archives of Plastic Surgery, 2017 Supported by recent literature on the signs of aging of the middle and lower face, our clinical research has documented a loss of volume of the deep structural components of the central face and a progressive descent of the nasolabial fat and the jowl fat, leading to facial fragmentation.

Lift observation conveys object weight distribution but partly enhances predictive lift planning [PDF]
Journal of Neurophysiology, 2020 AbstractObservation of object lifting allows updating of internal object representations for object weight, in turn enabling accurate scaling of fingertip forces when lifting the same object. Here, we investigated whether lift observation also enables updating of internal representations for an object’s weight distribution.
