Normalized lift: an energy interpretation of the lift coefficient simplifies comparisons of the lifting ability of rotating and flapping surfaces. [PDF]
PLoS ONE, 2012 For a century, researchers have used the standard lift coefficient C(L) to evaluate the lift, L, generated by fixed wings over an area S against dynamic pressure, ½ρv(2), where v is the effective velocity of the wing.

Moving Surface Boundary-Layer Control on the Wake of Flow around a Square Cylinder
Applied Sciences, 2022 In this paper, the entire process of the flow around a fixed square cylinder and the moving surface boundary-layer control (MSBC) at a low Reynolds number was numerically simulated.

Advanced Engineering Materials, EarlyView.Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Advanced Engineering Materials, EarlyView.Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.

On the topological bifurcation of flows around a rotating circular cylinder [PDF]
, 1997 Flow fields around a rotating circular cylinder in a uniform stream are computed using a low dimensional Galerkin method. Results show that the formation of a Fopple vortex pair behind a stationary circular cylinder is caused by the structural ...

Unstable inner cylinder whirl of concentric double rotating cylinder system
Mechanical Engineering Journal, 2022 This research investigated unstable inner cylinder whirl in a double rotating cylinder system in which the axis of the inner cylinder is supported elastically in the radial direction and the axis of the outer cylinder is fixed.

Unstable outer cylinder whirl of concentric double rotating cylinder system
Mechanical Engineering Journal, 2023 This research investigates unstable outer cylinder whirl in a double rotating cylinder system, with both co- and counter-rotation, in which the axis of the outer cylinder is supported elastically in the radial direction and the axis of the inner cylinder

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
