Abstract This paper reports on particle image velocimetry (PIV) measurements in compressible accelerated wake flows generated by two different central injector types, which are mounted a convergent-divergent nozzle. The injectors differ the extent of their trailing edge located either subsonic (injector A) or supersonic flow region B). In addition, undisturbed nozzle without is studied as refer...

The 2014 P5 report indicated the accelerator-based neutrino and rare decay physics research as a centrepiece of the US domestic HEP program at Fermilab. Operation, upgrade and development of the accelerators for the nearterm and longer-term particle physics program at the Intensity Frontier face formidable challenges. Here we discuss key elements of the accelerator physics and technology R&D pr...

EUROTRANS is a European research program for the transmutation of high level nuclear waste in an accelerator-driven system (ADS). As proposed, the driver linac needs to deliver a 2.5–4 mA, 600 MeV continuous-wave (CW) proton beam and later a 20 mA, 800 MeV one to the spallation target in the prototype-scale and industrial-scale demonstration phases, respectively. This paper is focusing on the c...

An optical method to determine the dynamic parameters of the transient response of an engine injector during its opening has been presented in this article. The method is based on measuring the transparency of a space into which the fuel is injected. The transparency measurements are realised by an optical instrument, which consists of both a transmitter and a detector oflR. radiation. A pair o...

During the process of containment depressurization venting, a high-temperature and high-pressure carrier gas with aerosol may be released into spent fuel pool by multihole injector. This in can removed scrubbing. A small-scale scrubbing facility was built to study phenomenon using In this study, gaseous mixture nitrogen steam is used simulate gas, insoluble solid particles TiO 2 are aerosols ga...

Aiming at the inherent problems of non-direct-drive injectors, such as long oil circuits and a difficult precise control needle stroke, based on structure direct-drive injector combined with demand for drive truck diesel injector, this study designs fabricates giant magnetostrictive actuator injectors. A simplified model is established, which mainly simplifies magnetization to facilitate subseq...

The use of optimum conventional growth hormone administration, using a growth hormone vial combined with an Auto Injector, was compared with a pen injection system using a cartridge of growth hormone. In both methods of administration the concentration of growth hormone was 16 IU/ml. Thirty patients (22 boys, eight girls) who had all previously been treated with growth hormone (4 IU/ml) adminis...

We describe the Object Infrastructure Framework, a system that seeks to simplify the creation of distributed applications by injecting behavior on the communication paths between components. We touch on some of the ilities and services that can be achieved with injector technology, and then focus on the uses of redirecting injectors, injectors that take requests directed at a particular server ...

Since fuel must be injected with appropriate pressure and time for accurate performance of diesel engines, then proper function of engine is influenced by accurate function of injector pump. At first total pump was designed by SolidWorks 2012 software. Then the total relationship of rotor, roller, internal cam ring, pole shoe and plunger in injector pump in MF285 tractor and their performance w...
