Being an energy source of another origin, the compression ignition (CI) engine’s typical design parameters might not suit Simarouba oil methyl ester (SuOME). Present experimental investigation targets are determining effects engine parameters, including fuel injection pressure and nozzle geometry, on engine, concerning performance emissions such as carbon monoxide (CO), unburnt hydrocarbon (HC)...

Laser-Doppler velocimetry measurements through a one millimeter hole in the casing of an annular turbine cascade were performed in the endwall region downstream of the blade row. Complementary threehole pressure probe measurements were also taken downstream of the nozzle blades, as well as blade surface pressure measurements. The object of this study was to devise methods for the measurement cl...

A numerical study of three-dimensional effects on the performance of a micronozzle fabricated from  at silicon wafers is performed by use of both continuum and kinetic approaches. The nozzle operates in a low-Reynoldsnumber regime, and viscous effects dominate the gas expansion. Thrust losses occur because the shear on the wall is greater in a  at nozzle conŽ guration than in an axisymmetric ...

In 1956, Truelove introduced the successful topical corticosteroid treatment for ulcerative colitis, using a modified blood transfusion set. To simplify the technique Matts (1960) introduced disposable plastic enema bags. We have extensively used both these methods. The modified blood transfusion set is better suited to inpatient than to out-patient treatment. The disposable bags, while simpler...

The objective of this study was the evaluation of spray volume and nozzle type effect on different formulation (water dispersible granules WG and oil dispersion OD) of two sulfonylurea herbicides: the mixture iodosulfuron methyl sodium + amidosulfuron and iodosulfuron methyl sodium + mesosulfuron methyl efficacy. There were investigated three levels of spray volume (125 l*ha, 250 l*ha and 350 l...

Aircraft noise is a complex topic which is projected to increase with the increasing number of aircraft and size of the engines. Turbine-powered aircraft produce sounds that are considered pollutants at certain decibel levels. Turbofan engines are inherently quieter than turbojet engines for a given level of thrust. The purpose of this research is to determine if current turbofan noise reductio...

Cavitation and turbulence in a diesel injector nozzle has a great effect on the development and primary breakup of spray. However, the mechanism of the cavitation flow inside the nozzle and its influence on spray characteristics have not been clearly known yet because of the internal nozzle flow complexities. In this paper, a comprehensive numerical simulation is carried out to study the intern...

compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (npr) have been numerically studied with severalturbulence models. the numerical results reveal that, the sst k–ω model give the bestresults compared with other models in time and accuracy. the effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...

Inkjet printing has been used as an additive manufacturing method to fabricate organic light emitting diode (OLED). By changing the type and proportion of solvent inks adjusting parameters ink droplets, uniform ejection multi-nozzle is achieved volume deviation jet controlled at about 5% when poly(3,4-ethy lenedioxythiohene) : poly (styrenesulfonate) (PEDOT:PSS), hole injection layer materials,...
