A computational study to investigate the influence of the orifices inclination and the rounding radius at the orifice inlet (consequence of the hydro-erosive grinding process applied after the orifices machining) over the ...

[EN] Diesel fuel injection systems are being used at higher injection pressure conditions over time because of more stringent emissions requirements. Thus, the importance to properly take into account the fluid compressibility ...

A computational study focused on the inner nozzle flow and cavitation phenomena has been reported in this paper in order to investigate the two most common types of diesel injector nozzles at the present: microsac and valve ...

[EN] Techniques from computational fluid dynamics (CFD) have been used to study Diesel injection process focus in the inner flow. The study has been perfmed taking into account different important physical and geometrical ...

One of the main aspects in the development of modern diesel engines has been the direct injection systems, due to its influence in the atomization and evaporation processes. The study of all physical and chemical phenomena ...

[EN] The geometry of diesel injector nozzles is known to significantly affect the characteristic spray behavior and emissions formation. In this paper, a novel nozzle concept, consisting of orifices with a convergent-divergent ...

[EN] In this paper, a high-resolution visualization technique has been used in combination with an extensively validated 0D model in order to relate the external structure of a diesel spray to the internal properties in ...
