Acoustic mixing at low Reynold’s numbers [PDF]
In microfluidic devices, hydrodynamic flow is usually governed by very low Reynold’s numbers. Under these conditions, only laminar flow is possible. Hence, mixing in microfluidics occurs by diffusion only. Interaction of small fluid volumes and acoustic waves in a solid leads to pronounced streaming effects in the fluid inducing mixing and stirring ...

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

Control surface effectiveness of low Reynolds number flight vehicles
Low-speed wind tunnel tests are carried out to investigate the control surface effectiveness at low Reynolds numbers (Re = 20,000-80,000). A thick airfoil, NACA0012, has a nonlinearity of the control surface effectiveness, which are associated with flow ...

Three-dimensional structure of a low-Reynolds-number turbulent boundary layer [PDF]
A low-Reynolds-number zero-pressure-gradient incompressible turbulent boundary layer was investigated using a volumetric imaging technique. The Reynolds number based on momentum thickness was 700.

Design of a control system for a 1.5 m diameter coaxial rigid rotor model
As a key equipment for rotor wind tunnel testing, the design specifications and control accuracy of the rotor test bench directly determine the testing accuracy and effectiveness of the rotor wind tunnel testing.

Effective swimming strategies in low Reynolds number flows
The optimal strategy for a microscopic swimmer to migrate across a linear shear flow is discussed. The two cases, in which the swimmer is located at large distance, and in the proximity of a solid wall, are taken into account.

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