the manner of spray the fuel has an important effect on stability and convenient mixture of fuel and oxidizer. swirl injectors because of formation of uniform spray cone and proper distribution of the fuel have been used in many rocket engines at aerospace industries. formation and development of air core in the interior stream of swirl injectors and simulation of them is complicated. double ba...
This paper presents numerical simulation results of the primary atomization of a turbulent liquid jet injected into a gaseous crossflow. Simulations are performed using the balanced force Refined Level Set Grid method. The phase interface during the initial breakup phase is tracked by a level set method on a separate refined grid. A balanced force finite volume algorithm together with an interf...
The Next Linear Collider (NLC) Injector System is designed to produce low emittance 8 GeV electron and positron beams at 120 hertz for injection into the NLC main linacs. Each beam consists of a 265 ns train of bunches (190 bunches spaced by 1.4 ns or 95 bunches spaced by 2.8 ns); each bunch has a population of up to 1.6x10 particles for 2.8 ns (or 0.8x10 particles for 1.4 ns). Horizontal and v...
CHAMBERS ACOUSTIC STABILITY Vladimir Bazarov Moscow Aviation Institute (State Technical University) 4, Volokolamskoe Shosse, Moscow 125080, RUSSIA E-mail: [email protected] Abstract Comparative analysis of the injector development history in order to eliminate acoustic instability in combustion chambers of LOX/kerosene big thrust engines both of gas generator and staged combustion cycle such as F-1, ...
Three high-pressure liquid injection machines were used to inject isazofos into the root zone of tuff;grass plots to evaluate its potential for control of Hoplolaimus galeatus and Tylenchorhynchus dubius. A Rogers root zone injector delivering isazofos at 2.3 kg a.i./ha through 30 degrees and 60 degrees spray tips at 5,000 psi (3.45 x 10 Pascals) significantly reduced nematode populations at 32...
We present results of the commissioning of a new injector for the Brazilian Synchrotron Light Source. The new injector consists of the existing 125-MeV LINAC and a new 500-MeV booster synchrotron. At present, about 40 mA can be injected into the booster and about 15 mA can be ramped up to 500 MeV at a repetition rate of 0.17 Hz. The new injector has allowed the accumulation of up to 540 mA in t...
Example 1: Fuel Injector Nozzle Diameters Problem A manufacturer of fuel injector nozzles installs a new digital measuring system. Investigators want to determine how well the new system measures the nozzles. Data set Nozzle.MPJ Description Variable Fuel injector nozzle measured Nozzle Data collection Technicians randomly sample, across all major sources of process variation (machine, time, shi...
1098-4402= We have conducted a multiobjective computational optimization of a high brightness, high average current photoinjector under development at Cornell University. This injector employs a dc photoemission electron gun. Using evolutionary algorithms combined with parallel computing resources, the multivariate parameter space of the photoinjector was explored for optimal values. This power...
