Experimental Characteristics of Crossed-Field Space-Charge Flows [PDF]

Journal of Applied Physics, 1966
An experimental method is described for determining the characteristics of space-charge flow in crossed electric and magnetic fields. A beam-intercepting system, which consists of a movable grid of wires biased at appropriate potentials, is inserted across the space-charge flow.

A Model for TSUnami FLow INversion from Deposits (TSUFLIND)

, 2015
Modern tsunami deposits are employed to estimate the overland flow characteristics of tsunamis. With the help of the overland-flow characteristics, the characteristics of the causative tsunami wave can be estimated.

Unsteady characteristics of a slat-cove flow field

Physical Review Fluids, 2018
The slat flow field of a multi-element airfoil is experimentally studied. Mean turbulence statistics and phase-locked data link shear layer structures to narrowband peaks in the surface pressure spectra. Most notably, a bulk cove oscillation related to shear layer flapping is found.

Characteristics of River Flows by Field Measurements

PROCEEDINGS OF HYDRAULIC ENGINEERING, 1991
The turbulent fluctuations of velocity have been measured actual rivers in the field where the relative water depth to roughness height is small, using ultrasonic flowmeter. The turbulent structures of river flows where roughness is relatively small, are similar to those in laboratory channels with the smooth bed.

Effect of induced magnetic field on peristaltic flow of a micropolar fluid in an asymmetric channel [PDF]

, 2010
Of concern in this paper is an investigation of peristaltic transport of a physiological fluid in an asymmetric channel under long wave length and low-Reynolds number assumptions. The flow is assumed to be incompressible, viscous, electrically conducting

Magnetic field correlations in a random flow with strong steady shear

, 2010
We analyze magnetic kinematic dynamo in a conducting fluid where the stationary shear flow is accompanied by relatively weak random velocity fluctuations. The diffusionless and diffusion regimes are described.

Numerical Study on the Operational Ventilation Patterns of Alternative Jet Fans in Curved Tunnels

Buildings
In tunnel operation ventilation systems, the arrangement of jet fans plays a decisive role in ensuring ventilation efficiency. Curved tunnels, due to their unique radius of curvature, exhibit significant differences in fan installation parameters and jet
