Wing Efficiency Enhancement at Low Reynolds Number
AerospaceThe aerodynamic performance of wings degrades severely at low Reynolds number; lift often becomes non-linear, while drag increases significantly, caused by large extents of separation.

Local vibrations and lift performance of low Reynolds number airfoil
Propulsion and Power Research, 2017 The 2D incompressible Navier-Stokes equations are solved based on the finite volume method and dynamic mesh technique is used to carry out partial fluid structure interaction.

Characterizing Elastic Turbulence in Channel Flows at Low Reynolds number [PDF]
, 2016 We experimentally investigate the flow of a viscoelastic fluid in a parallel shear geometry at low Reynolds number. As the flow becomes unstable via a nonlinear subcritical instability, velocimetry measurements show non-periodic fluctuations over a broad

Aerodynamic Performance of Micro Aerial Wing Structures at Low Reynolds Number [PDF]
INCAS Bulletin, 2019 Corrugations are folds on a surface as found on wings of dragon fly insects. Although they fly at relatively lower altitudes its wings are adapted for better aerodynamic and aero-elastic characteristics. In the present work, three airfoil geometries were

Hydrodynamic synchronisation of non-linear oscillators at low Reynolds number
, 2012 We introduce a generic model of weakly non-linear self-sustained oscillator as a simplified tool to study synchronisation in a fluid at low Reynolds number. By averaging over the fast degrees of freedom, we examine the effect of hydrodynamic interactions

Numerical Investigation on Flow Separation Control of Low Reynolds Number Sinusoidal Aerofoils [PDF]
, 2016 The paper presents a computational analysis of the characteristics of a NACA 634- 021 aerofoil incorporated with sinusoidal leading-edge protuberances at Re = 14,000. The protuberances are characterized by an amplitude and wavelength of 12% and 50% of

NUMERICAL INVESTIGATION OF TWO ELEMENT CAMBER MORPHING AIRFOIL IN LOW REYNOLDS NUMBER FLOWS [PDF]
Journal of Engineering Science and Technology, 2017 Aerodynamic performance of a two-element camber morphing airfoil was investigated at low Reynolds number using the transient SST model in ANSYS FLUENT 14.0 and eN method in XFLR5. The two-element camber morphing concept was employed to morph the baseline

Filament actuation by an active colloid at low Reynolds number
New Journal of Physics, 2017 Active colloids and externally actuated semi-flexible filaments provide basic building blocks for designing autonomously motile micro-machines. Here, we show that a passive semi-flexible filament can be actuated and transported by attaching an active ...
