Study on flow separation and transition of the airfoil in low Reynolds number
The Physics of Fluids, 2019As typical flow characteristics in a low Reynolds number, laminar separation bubbles (LSBs) and transition to turbulence over airfoils have been extensively studied in recent years.

In nature, liquid propulsion in low‐Reynolds‐number regimes is often achieved by arrays of beating cilia with various forms of motion asymmetry. In particular, spatial asymmetry, where the cilia follow a different trajectory in their effective and ...

A low Reynolds number flow and heat transfer topology of a cylinder in a wake
The Physics of Fluids, 2018The flow and heat transfer topology of an isothermal cylinder (diameter D) in the wake of another smaller (diameter d) cylinder is numerically investigated for a spacing ratio of L/d = 5.5 and at a Reynolds number of 200.

Transonic low-Reynolds number airfoils
Journal of Aircraft, 1991Airfoils operating in the unexplored high-Mach—low-Reynolds number regime are computationally investigated. The motivations are 1) quantificatio n of achievable airfoil performance levels; 2) quantificatio n of parameter sensitivities which impact vehicle sizing; 3) identification of possible shortcomings in the computational methods employed; and 4 ...

Newton’s second law of motion stipulates that the rate of change of momentum of a fluid parcel must be balanced by the body force exerted over the parcel volume and by the surface force exerted on the parcel boundary. Under certain conditions, the rate of change of momentum of the parcel is small compared to the body and surface force, and can be ...

Effects of kinematic parameters on three-dimensional flapping wing at low Reynolds number
The Physics of Fluids, 2018In nature, creatures such as birds, insects, and fish have excellent flight and mobility capabilities. The prominent flight performance of many creatures employing flapping wings has attracted researchers to study the aerodynamics of bionic flapping ...

Self-Propulsion at Low Reynolds Number
Physical Review Letters, 1987We formulate the problem of self-propulsion at low Reynolds number in terms of a gauge field over the space of shapes. The computation of this field is discussed, and carried out in some examples. We apply our results to determine maximally efficient infinitesimal swimming motions of spheres and circular cylinders.

Quiet swimming at low Reynolds number
Physical Review E, 2015The stresslet provides a simple model of the flow created by a small, freely swimming and neutrally buoyant aquatic organism and shows that the far field fluid disturbance created by such an organism in general decays as one over distance squared. Here we discuss a quieter swimming mode that eliminates the stresslet component of the flow and leads to a

Low Reynolds number suspension gravity currents
The European Physical Journal E, 2013The extension of a gravity current in a lock-exchange problem, proceeds as square root of time in the viscous-buoyancy phase, where there is a balance between gravitational and viscous forces. In the presence of particles however, this scenario is drastically altered, because sedimentation reduces the motive gravitational force and introduces a finite ...

In this chapter, we provide a brief description of some of the main results of low-Reynolds-number hydrodynamics. In particular, we introduce the general subject by way of several example flows and provide derivations or explanations of some of the fluid dynamics themes that are used in later chapters of this book: channel flows, Darcy’s approximation,
