On-Surface Locomotion of Particle Based Microrobots Using Magnetically Induced Oscillation
Micromachines, 2017 The low Reynolds number condition presents a fundamental constraint on designing locomotive mechanisms for microscale robots. We report on the use of an oscillating magnetic field to induce on-surface translational motion of particle based microrobots ...

The pressure moments for two rigid spheres in low-Reynolds-number flow [PDF]
, 1993 The pressure moment of a rigid particle is defined to be the trace of the first moment of the surface stress acting on the particle. A Faxén law for the pressure moment of one spherical particle in a general low-Reynolds-number flow is found in terms of ...

Steady flow over triangular extended solid attached to square cylinder – A method to reduce drag
Ain Shams Engineering Journal, 2015 Numerical analysis of two dimensional steady flows over a triangular extended solid (thorn) attached to square cylinder positioned at front stagnation point and at rear stagnation point separately is reported at low Reynolds number (Re = 40).

Fluid Elasticity Can Enable Propulsion at Low Reynolds Number [PDF]
, 2012 Conventionally, a microscopic particle that performs a reciprocal stroke cannot move through its environment. This is because at small scales, the response of simple Newtonian fluids is purely viscous and flows are time-reversible.

On the aerodynamic forces on heaving and pitching airfoils at low Reynolds number [PDF]
Journal of Fluid Mechanics, 2017 The influence that the kinematics of pitching and heaving 2D airfoils has on the aerodynamic forces is investigated using direct numerical simulations and a force decomposition algorithm. Large-amplitude motions are considered (of the order of one chord),

Low Reynolds Number Airfoil Evaluation for the Mars Helicopter Rotor
Proceedings of the Vertical Flight Society 74th Annual Forum, 2018 The present research provides a performance comparison between several low Reynolds number airfoil profiles for the Mars Helicopter. The low density of the Martian atmosphere and the relatively small Mars Helicopter rotor result in very low chord-based

Numerical Computation of Low Reynolds Number Viscous Flow Past Bluff Bodies
International Journal of Applied Mechanics and Engineering, 2020 This article presents a two-dimensional steady viscous flow simulation past circular and square cylinders at low Reynolds numbers (based on the diameter) by the finite volume method with a non-orthogonal body-fitted grid. Diffusive fluxes are discretized

Aerodynamics of two-dimensional bristled wings in low-Reynolds-number flow
AIP Advances, 2021 The smallest flying insects commonly possess bristled wings and use drag to provide flight forces. A bristled wing, with a wing area about 10% of that of a flat-plate wing, operating at the relevant Reynolds number of 5–15, produces a drag close to the ...
