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.

Numerical Validation of a Multi-Dimensional Similarity Law for Scaled STOVL Aircraft Models

Aerospace
The complex jet-ground interactions of Short Take-off and Vertical Landing (STOVL) aircraft are critical to flight safety and performance, yet studying them with traditional full-scale wind tunnel tests is prohibitively expensive and time-consuming ...

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 ...

Low-Reynolds number swimming in gels

, 2010
Many microorganisms swim through gels, materials with nonzero zero-frequency elastic shear modulus, such as mucus. Biological gels are typically heterogeneous, containing both a structural scaffold (network) and a fluid solvent.

Hydromechanics of low-Reynolds-number flow. Part 4. Translation of spheroids [PDF]

, 1976
The problem of a uniform transverse flow past a prolate spheroid of arbitrary aspect ratio at low Reynolds numbers has been analysed by the method of matched asymptotic expansions. The solution is found to depend on two Reynolds numbers, one based on the

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

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 ...
