Venturi injector is widely used in fertigation system due to its obvious advantages such as cheap and robust system without mobile pieces, simple structure, convenient to operation, stable performance, needless of external energy for operation etc. At present, the hydraulic parameters such as suction capacity (injection rate) for the most of the Venturi injectors produced domestically are not v...

014202-1 A multibeamlet approach to a high current ion injector, whereby a large number of beamlets are accelerated and then merged to form a single beam, offers a number of potential advantages over a monolithic single beam injector. These advantages include a smaller transverse footprint, more control over the shaping and aiming of the beam, and more flexibility in the choice of ion sources. ...

A buried injector is proposed as a source of electrons for substrate hot electron injection. To enhance the compatibility with VLSI processing, the buried injector is formed by the local overlap of the n-well and p-well of a retrograde twin-well CMOS process. The injector is activated by means of punchthrough. This mechanism allows the realization of a selective injector without increasing the ...

UNLABELLED BACKGROUNDAIM: In growth disorders, ensuring long-term growth hormone therapy (GHT) remains a challenge that might compromise the clinical outcome. Consequently, strategies aiming at alleviating the burden of daily injection might improve the treatment benefit. The study reported here was performed to assess the ease of use of Norditropin NordiFlex(®) (Novo Nordisk, Princeton, NJ, US...

Fuel injection is systems for supplying high pressurize fuel to maximum mixing of fuel with air in an internal combustion engine. Direct Injection (DI) Systems as used in DI engines, in which the fuel is injected directly into a combustion chamber formed in the clylinder itself. The fuel injector directly injects fuel into the direct fuel injection system. The injector is a very complicated par...

Diesel engines injection process is essential for optimum operation to maintain the design power and torque requirements and to satisfy stricter emissions legislations. In general this process is highly dependent upon the injection pump and fuel injector health. However, extracting such information about the injector condition using needle movements or vibration measurements without affecting i...

OBJECTIVE The aim of this study was to compare flow rates over time and the deviations from the target flow rate of a magnetic resonance imaging contrast agent achieved by an automated injector versus manual injection. MATERIALS AND METHODS In this laboratory study, the magnetic resonance contrast agent gadobutrol was repeatedly injected by an injector and by 10 experienced technologists. Six...

In this study, water and air were used as simulated media to investigate the spray characteristics of a gas-centered swirl coaxial (GCSC) injector under different ambient pressures through experimental, simulation, theoretical approaches. The results showed that for same liquid mass flow rate, breakup length film decreased with increasing pressure, extent decrease diminishing pressure increased...

We report, the use of laser-plasma-driven x rays to reveal three-dimensional (3D) structure a highly atomizing water spray. Soft approximately 5 keV are generated by means laser-plasma accelerator. Transmission radiography measurements performed at different angles, rotating multihole injector. Using computer tomography, local liquid volume distribution and its spatial variation retrieved in 3D...
