Mechanism of Magnetic Flux Leakage Detection Method Based on the Slotted Ferromagnetic Lift-Off Layer

open access: yesSensors, 2022
Magnetic flux leakage (MFL) testing is widely used in non-destructive testing of ferromagnetic components. In view of the serious attenuation of the leakage magnetic field (LMF) caused by the transmission of LMF in the lift-off layer between the ...

Fluid dynamic analysis and lift enhancement of material transport and mixing around airfoil through Lagrangian coherent structures

open access: yesResults in Engineering, 2023
Flow separation around an airfoil can be effectively controlled by appropriately positioning a synthetic jet (SJ) on the airfoil surface, subsequently enhancing the airfoil's lift.

Lift observation conveys object weight distribution but partly enhances predictive lift planning [PDF]

open access: yesJournal 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.

Experimental Investigation on the Combined Blowing Control of a Hybrid Wing Body Aircraft

open access: yesActuators, 2023
Combined blowing was performed on a Hybrid Wing Body (HWB) aircraft through wind tunnel testing at a Reynolds number of 1.75 × 106. The full cycle of separation and reattachment under the control of combined blowing was implemented using Computational ...

Evolution of the leading-edge vortex over a flapping wing mechanism

open access: yesJournal of Mechanical Engineering and Sciences, 2020
Leading-edge vortex governs the aerodynamic force production of flapping wing flyers. The primary factor for lift enhancement is the leading-edge vortex (LEV) that allows for stall delay that is associated with unsteady fluid flow and thus generating ...

Coriolis effects enhance lift on revolving wings [PDF]

open access: yesPhysical Review E, 2015
At high angles of attack, an aircraft wing stalls. This dreaded event is characterized by the development of a leading edge vortex on the upper surface of the wing, followed by its shedding which causes a drastic drop in the aerodynamic lift. At similar angles of attack, the leading edge vortex on an insect wing or an autorotating seed membrane remains
