On Molecular Flow Velocity Meters [PDF]
IEEE Transactions on Molecular, Biological and Multi-Scale Communications, 2021 Flow velocity is an important characteristic of the fluidic mediums. In this paper, we introduce a molecular based flow velocity meter consisting of a molecule releasing node and a receiver that counts these molecules. We consider both flow velocity detection and estimation problems, which are employed in different applications.

A flowmeter for measuring the dispersed phase velocity in multiphase flow with non-uniform velocity profile [PDF]
, 2008 This study aims to introduce a new technique to measure the velocity distribution of the dispersed component of a vertical, upward, water continuous two-phase pipe flow. Here, it is proposed that measurements of the variation in the local conductance

Coherence of Velocity Fluctuations in Turbulent Flows [PDF]
Physical Review Letters, 2022 We investigate the spatio-temporal quantity of coherence for turbulent velocity fluctuations at spatial distances of the order or larger than the integral length scale $l_{0}$. Using controlled laboratory experiments, an exponential decay as a function of distance is observed with a decay rate which depends on the flow properties.

Aspect angle dependence of the E region irregularity velocity at large flow angles [PDF]
, 2007 We present the Doppler velocity observations of 1-m plasma waves in the auroral E region by the Scandinavian Twin Auroral Radar Experiment (STARE) Norway VHF coherent radar in the context of simultaneous and coincident measurements of electron and ion ...

Flow velocities of Alaskan glaciers [PDF]
Nature Communications, 2013 Our poor understanding of tidewater glacier dynamics remains the primary source of uncertainty in sea level rise projections. On the ice sheets, mass lost from tidewater calving exceeds the amount lost from surface melting. In Alaska, the magnitude of calving mass loss remains unconstrained, yet immense calving losses have been observed.

Velocity inversion in nanochannel flow [PDF]
Physical Review E, 2007 The nanoscale cylindrical Couette flow is investigated by means of molecular dynamics simulations, in the case where the inner cylinder is rotating whereas the outer cylinder is at rest. We find that the tangential velocity of the low is inverted when the fluid-wall interaction near the outer cylinder is weak and the fluid density is low.

Flow-distributed oscillation, flow-velocity modulation, and resonance [PDF]
Physical Review E, 2005 We examine the effects of a periodically varying flow velocity on the standing and travelling wave patterns formed by the flow-distributed oscillation (FDO) mechanism. In the kinematic (or diffusionless) limit, the phase fronts undergo a simple, spatiotemporally periodic longitudinal displacement.
