For every cycle of the SLC, the injector is required to launch two electron bunches and a single positron bunch into their rsspective emittance damping rings. Each bunch is to have a population of 7.5 x 10” particles/bunch, an energy of 1.21 GeV, and a full width energy spread of less than 2%. The electron beams are produced from a thermionic cathode, bunched, and accelerated to about 200 MeV. ...

Shear coaxial injectors are a common injector type for liquid-rocket-propulsion applications and can be found in many oxygen/hydrogen engines. These injectors rely on the shear between an outer lower-density, high-velocity annulus and a higher-density, low-velocity inner jet to atomize and mix the propellants. Because of the dense-jet core, the optical densities of these sprays are high, partic...

This study is conducted to investigate efficacy of an insulin jet injector and an insulin pen in treatment of type 2 diabetic patients. Sixty patients with type 2 diabetes were treated with rapid-acting insulin (regular insulin) and insulin analog (insulin aspart) using the jet injector and the pen in 4 successive test cycles. Postprandial glucose and insulin concentrations in blood were measur...

The CLIC Test Facility (CTF3) is an intermediate step to demonstrate the technical feasibility of the key concepts of the new RF power source for CLIC. CTF3 will use electron beams with an energy range adjustable from 170 MeV (3.5 A) to 380 MeV (with low current). The injector is based on a thermionic gun followed by a classical bunching system embedded in a long solenoidal field. As an alterna...

Variation of fuel properties occurring during extreme fuel pressurisation in Diesel fuel injectors relative to those under atmospheric pressure and room temperature conditions may affect significantly fuel delivery, fuel injection temperature, injector durability and thus engine performance. Indicative results of flow simulations during the full injection event of a Diesel injector are presente...

In this paper, an analytical solution for computing the plastic & linear plastic stresses and critical angular velocity in a FGM hollow & solid rotating disk is developed. It has been assumed that the modulus of elasticity and yield strength were varying through thickness of the FGM material according to a power law relationship. The Poisson's ratio were considered constant throughout the thick...

Abstract During the ignition of a swirled single-injector combustor, two phases have been identified experimentally. In first, flame penetrates injection unit, while in second, lifts off after substantial delay before stabilizing at distance from injector. This transient phenomenon is investigated using Large Eddy Simulations based on an Euler–Lagrange description liquid spray, energy depositio...

A vertically integrated alternative for integrated injection logic has been realized, named buried injector logic (BIL). 1 MeV ion implantations are used to create buried layers. The vertical pnp and npn transistors have thin base regions and exhibit a limited charge accumulation if a gate is saturated. d.c. and dynamic analysis of BIL-gate behaviour are given. A minimum gate delay of well belo...

A rotating detonation rocket engine (RDRE) with various convergent nozzles and chamber lengths is investigated. Three hundred hot-fire tests are performed using methane oxygen ranging from equivalence ratio equaling 0.5–2.5 total propellant flow up to 0.680 kg/s. For the full-length (76.2 mm) study, three at contraction ratios ϵc = 1.23, 1.62 2.40 tested. Detonation exhibited for each geometry ...
