The paper presents unique research results on the effect of coking diesel engine injector nozzles powered by mixtures 10%, 20% and 30% biomethanol fuel compared to being supplied with pure fuel. test results, obtained from an experiment conducted in accordance ISO 15550-1 standard, show legitimacy using as additive due lower nozzles, which has a positive impact reduction pollutant emissions dur...

The Laval nozzle is a very widely used device that has made great contributions due to its invention in aerospace, mechanical engineering, applied chemistry etc. development of many modern technologies relies on the establishment nozzles. In this paper, current research advances numerical simulation methods flow and nozzle-related investigation or applications different fields are reviewed. For...

An experimental investigation was performed of the acoustic effects of jet-pylon interaction for separate flow and chevron nozzles of both bypass ratio five and eight. The models corresponded to an approximate scale factor of nine. Cycle conditions from approach to takeoff were tested at wind tunnel free jet Mach numbers of 0.1, 0.2 and 0.28. An eight-chevron core nozzle, a sixteen chevron fan ...

in high-pressure axial turbines, when the fluid mass flow is low, the supersonic blades are being used to obtain a high specific work output. to prevent losses due to low blade aspect ratio, the turbine is used in partial admission conditions. the turbine stator is a group of convergence-divergence nozzles that provides the supersonic flow. the design of these nozzles is important, because ther...

Metallurgical aggregates, which are used for metal waste melting, equipped with lances blowing gaseous media. These media allow especially scrap melting and intense homogenization of the resulting melt. In connection this, systems developed both itself on bath surface or into melt gas mixture powdered substances. When designing individual lance tips nozzles, it is necessary to respect certain c...
