Low Reynolds Number Flow Around Tori of Different Slenderness Γ

Applied Sciences, 2017
We present the results of axisymmetric and three-dimensional numerical simulations of the flow around a torus in the low Reynolds number regime [ 10 − 2 ; 3 × 10 3 ] and aspect-ratio 0 < Γ = 2 a / R ≤ 2 (core diameter ...

Dynamics and Stability of Low-Reynolds-Number Swimming Near a Wall [PDF]

, 2011
The locomotion of microorganisms and tiny artificial swimmers is governed by low-Reynolds-number hydrodynamics, where viscous effects dominate and inertial effects are negligible.

Two-sphere low-Reynolds-number propeller [PDF]

Physical Review E, 2010
A three-dimensional model of a low-Reynolds-number swimmer is introduced and analyzed in this Brief Report. This model consists of two large and small spheres connected by two perpendicular thin rods. The geometry of this system is motivated by the microorganisms that use a single tail to swim; the large sphere represents the head of microorganism and ...

Low Reynolds number hydrodynamics of asymmetric, oscillating dumbbell pairs

, 2010
Active dumbbell suspensions constitute one of the simplest model system for collective swimming at low Reynolds number. Generalizing recent work, we derive and analyze stroke-averaged equations of motion that capture the effective hydrodynamic far-field ...

A new friction factor relationship for fully developed pipe flow [PDF]

, 2005
The friction factor relationship for high-Reynolds-number fully developed turbulent pipe flow is investigated using two sets of data from the Princeton Superpipe in the range 31×10^3 ≤ ReD ≤ 35×10^6. The constants of Prandtl’s ‘universal’ friction factor

Wing Efficiency Enhancement at Low Reynolds Number

Aerospace
The 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.

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
