Experimental Investigation of Turbulence Promoters effect on Characteristics of Wake related to Linear Compressor Cascade [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2014
In this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. To do this, two wires were implemented

Nanometer Layer Coating to Lactose Particles for Optimization of Dexamethasone Pulmonary Delivery

Advanced Science, EarlyView.
Nanometer layer coating (NLC) was investigated and its mechanism illustrated by advanced characterization techniques. The effects and application for the inhalation of dexamethasone (DEX) were demonstrated through in vitro and in vivo evaluation. This approach increased DEX bioavailability and enabled the dose to be reduced to 1/30 of the intravenous ...

Neuromorphic Optical Tracking and Imaging of Randomly Moving Targets Through Dynamic Dense Scattering Media

Advanced Science, EarlyView.
Vision begins not with images but with change: the retina fires only when something moves, handing the brain a stream of spikes. A neuromorphic imaging system adopts the same strategy—an event sensor that sees like the retina, a spiking network that thinks like the brain—to track and reconstruct fully randomly moving targets through tissue (phantom ...

Gravity wave turbulence in a laboratory flume [PDF]

, 2007
We present an experimental study of the statistics of surface gravity wave turbulence in a flume of a horizontal size 12×6  m. For a wide range of amplitudes the wave energy spectrum was found to scale as Eω∼ω-ν in a frequency range of up to one decade ...

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Coherent optical binary polarisation shift keying heterodyne system in the free-space optical turbulence channel [PDF]

, 2011
In this paper, analytical and simulation results for the bit error rate (BER) performance and fading penalty of a coherent optical binary polarization shift keying (2PolSK) heterodyne system adopted for a free space optical (FSO) communication link ...

Acoustically Activatable Drug‐Loaded Nanodroplets for Mechanochemical Therapy in Solid Tumors

Advanced Science, EarlyView.
Microfluidically fabricated drug‐loaded nanodroplets are sequentially activated by dual‐frequency ultrasound through acoustic droplet vaporization followed by bubble collapse, enabling spatially controlled drug release and mechanical tumor fractionation, resulting in synergistic mechanochemotherapy and prolonged survival.

Study on Turbulence Intensity Calculated by WT for Safety Assessment of Wind Farms

Kongzhi Yu Xinxi Jishu, 2013
Turbulence intensity has an important effect on fatigue load and ultimate load of wind turbine. Based on the wind measurement data of a wind farm in the Yunnan-Guizhou plateau, the turbulence intensity was calculated by CFD software Meteodyn WT ...

Study on the Wake of a Miniature Wind Turbine Using the Reynolds Stress Model

Energies, 2016
The Reynolds Stress Model (RSM) is adopted to simulate the wind turbine wake and the simulation results are compared with the wind tunnel test data, simulation results from the standard k-ε model and a modified k-ε model.

Investigating whether the turbulence model from existing small wind turbine standards is valid for rooftop sites [PDF]

, 2011
The wind energy industry has developed considerably in recent years with regard to large scale wind turbines. However, the small wind turbines (SWTs) are still underdeveloped. The classification of SWTs comes under the standard IEC6140001-2. When a small
