Performance analysis of an undershot cross-flow water turbine based on the flow near the runner

Nihon Kikai Gakkai ronbunshu, 2016
Since the great east Japan earthquake in 2011, renewable energy is turned into importance. Hydro power is one of most important energies because it is not affected by weather condition and possible to generate steady quantity electric power, so it could ...

Effect of Shape of Sedient Particles at the Bed of Open Channel on Friction Coefficient [PDF]

علوم و مهندسی آبیاری, 2009
Hydraulic calculations of the flow in channel and over bank areas of flood plains require an evaluation of roughness characteristics. The Manning roughness coefficient (), Chesy coefficient () and Darsy-Weisbach coefficient () are used to describe the ...

Spatial interpolation of point velocities in stream cross-section

Journal of Hydrology and Hydromechanics, 2015
The most frequently used instrument for measuring velocity distribution in the cross-section of small rivers is the propeller-type current meter. Output of measuring using this instrument is point data of a tiny bulk.

The response of the tandem pore potassium channel TASK-3 (K2P9.1) to voltage : gating at the cytoplasmic mouth [PDF]

, 2009
Although the tandem pore potassium channel TASK-3 is thought to open and shut at its selectivity filter in response to changes of extracellular pH, it is currently unknown whether the channel also shows gating at its inner, cytoplasmic mouth through ...

Modeling and Analysis of Fluid Flow through A Non-Prismatic Open Channel with Application to Drilling [PDF]

Modeling, Identification and Control, 2018
This paper presents the development and validation of a simplified dynamic model of a Venturi channel. The existing dynamic models on open channels are based on the open channel flow principles, which are the shallow water equations.

Computational Fluid Dynamics Analysis of Cavitating Hydrofoils Near the Sea Surface in Supercritical Open Channel Flows [PDF]

Journal of Applied Fluid Mechanics
As a high-speed submerged body travels beneath the water surface, it induces deformation of the free surface and may generate cavitation due to local pressure reductions.

Distribution of motion scales of vortices in turbulent open channel flow

Shui kexue jinzhan, 2015
To understand the distribution of motion scales of vortices in turbulent open channel flow along water depth. A flume experiment system based on high-resolution particle image velocimetry(PIV) was applied to measure fully developed turbulent open channel

Identification of putative potassium channel homologues in pathogenic protozoa [PDF]

, 2012
K(+) channels play a vital homeostatic role in cells and abnormal activity of these channels can dramatically alter cell function and survival, suggesting that they might be attractive drug targets in pathogenic organisms.

Recovery from open channel block by acetylcholine during neuromuscular transmission in larval zebrafish [PDF]

, 2000
At larval zebrafish neuromuscular junctions (NMJs), miniature end plate currents (mEPCs) recorded in vivo have an unusually fast time course. We used fast-flow application of acetylcholine (ACh) onto outside-out patches to mimic the effect of synaptic ...
