Self-learning how to swim at low Reynolds number [PDF]
, 2018 Synthetic microswimmers show great promise in biomedical applications such as drug delivery and microsurgery. Their locomotion, however, is subject to stringent constraints due to the dominance of viscous over inertial forces at low Reynolds number (Re ...

Acoustic mixing at low Reynold’s numbers [PDF]
Applied Physics Letters, 2006 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 ...

Flow characteristics over NACA4412 airfoil at low Reynolds number
EPJ Web of Conferences, 2016 In this study, the flow phenomena over NACA4412 were experimentally observed at various angle of attack and Reynolds number of 25000, 50000 and 75000, respectively.

Control surface effectiveness of low Reynolds number flight vehicles
Journal of Fluid Science and Technology, 2014 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 ...

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

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