Examining the Velocity field and the effects of hydraulic and geometrical parameters on the amount of the sediment entering the diversion channels through using Artificial Neural Network and ANSYS-CFX Software [PDF]
مهندسی منابع آب, 2019 Intakes are one of the varied types of channel and river- water- intake structures. The experimental model is first simulated through ANSYS- CFX software. The verification results indicate that the results of the numerical model correspond fairly well to

VELOCITY FIELD IN A STEADY BREAKER
Coastal Engineering Proceedings, 1980 An experimental investigation is described of the velocity field in a steady, spilling-type breaker, generated on a steady current by a submerged hydrofoil. Velocities have been measured with a laser-doppler system, and analysed with respect to mean and rms-values as well as Reynolds stresses.

The properties of cosmic velocity fields [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Understanding the velocity field is very important for modern cosmology: it gives insights to structure formation in general, and also its properties are crucial ingredients in modelling redshift-space distortions and in interpreting measurements of the kinetic Sunyaev-Zeldovich effect. Unfortunately, characterising the velocity field in cosmological N-

Protostellar Jet and Outflow in the Collapsing Cloud Core
, 2009 We investigate the driving mechanism of outflows and jets in star formation process using resistive MHD nested grid simulations. We found two distinct flows in the collapsing cloud core: Low-velocity outflows (sim 5 km/s) with a wide opening angle ...

The Large-Scale Velocity Field [PDF]
, 1996 I summarize both observational and theoretical developments in the last few years in measuring and understanding the large-scale velocity field of galaxies, with special attention to the bulk flow, or average peculiar velocity, within spheres centered on

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Influence of Plasma Sheath’s Velocity Field on ISAR Imaging of Hypersonic Target
Remote Sensing, 2022 Plasma sheath poses a serious challenge to inverse synthetic aperture radar (ISAR) imaging of hypersonic targets. This paper investigated the distribution characteristics of the electron density and velocity field in the plasma sheath surrounding the ...
