The aerodynamic effects of wing–wing interaction in flapping insect wings [PDF]
, 2005 We employed a dynamically scaled mechanical model of the small fruit fly Drosophila melanogaster (Reynolds number 100–200) to investigate force enhancement due to contralateral wing interactions during stroke reversal (the 'clap-and-fling').

Lift Enhancement of a Stationary Wing in a Wake
AIAA Journal, 2020 A stationary wing placed in the wake of a bluff body experiences lift enhancement. The quasi-periodic flow in the wake causes excitation of the separated flow in the poststall conditions.

Results 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.

Closed-loop Flow Control Method Based on Deep Reinforcement Learning using a Co-flow Jet [PDF]
Journal of Applied Fluid MechanicsA closed-loop control framework is developed for the co-flow jet (CFJ) airfoil by combining the numerical flow field environment of a CFJ0012 airfoil with a deep reinforcement learning (DRL) module called tensorforce integrated in Python.

Skin Application of Menthol Enhances Maximal Isometric Lifting Performance [PDF]
Journal of Strength & Conditioning Research, 2023 Abstract Over, DM, Arjomandkhah, N, Beaumont, JD, Goodall, S, and Barwood, MJ. Skin application of menthol enhances maximal isometric lifting performance. J Strength Cond Res 37(3): 564–573, 2023—Topical application of menthol to the skin improves perception (i.e., makes subjects feel cooler) and changes submaximal neuromuscular recruitment ...

Using a categorisation structure to understand interaction in children’s books [PDF]
, 2013 Children’s books can vary greatly in the type of and depth of interaction that is required from the reader. The types of interaction demanded by different types of books can be explored using contrasting paradigms.

Lift-enhancing tabs on multielement airfoils [PDF]
Journal of Aircraft, 1995 The use of flat-plate tabs (similar to Gurney flaps) to enhance the lift of multielement airfoils is extended here by placing them on the pressure side and near the trailing edge of the main element rather than just on the furthest downstream wing element. The tabs studied range in height from 0.125 to 1.25% of the airfoil reference chord. In practice,

Object-guided Spatial Attention in Touch: Holding the Same Object with Both Hands Delays Attentional Selection [PDF]
, 2009 Previous research has shown that attention to a specific location on a uniform visual object spreads throughout the entire object. Here we demonstrate that, similar to the visual system, spatial attention in touch can be object guided.

Wing flexibility enhances load-lifting capacity in bumblebees [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2013 The effect of wing flexibility on aerodynamic force production has emerged as a central question in insect flight research. However, physical and computational models have yielded conflicting results regarding whether wing deformations enhance or diminish flight forces. By experimentally stiffening the wings of live bumblebees, we demonstrate that wing

Bubbly and Buoyant Particle-Laden Turbulent Flows [PDF]
, 2020 Fluid turbulence is commonly associated with stronger drag, greater heat transfer, and more efficient mixing than in laminar flows. In many natural and industrial settings, turbulent liquid flows contain suspensions of dispersed bubbles and light ...
