Diesel nozzle geometry influence on spray liquid-phase fuel penetration in evaporative conditions
TLDR
In this article, an experimental study of real multi-hole Diesel nozzles is performed under current DI Diesel engines operating conditions. The aim of the investigation is to study the influence of orifice geometry on the flow at the nozzle exit and to analyse its effect on the spray in evaporative conditions.About:

Effect of nozzle orifice geometry on spray, combustion, and emission characteristics under diesel engine conditions
TL;DR: In this article, the effects of orifice geometry on inner nozzle flow, spray, and combustion processes are examined by coupling the injector flow and spray simulations, showing that conicity and hydrogrinding reduce cavitation and turbulence inside the nozzle orifice, which slows down primary breakup, increasing spray penetration, and reducing dispersion.

The influence of cavitation on the internal flow and the spray characteristics in diesel injection nozzles
TL;DR: In this paper, a study was carried out on the influence of cavitation on the internal flow and the macroscopic behavior of the spray in Diesel injection nozzles, and the results of this hydraulic characterisation, together with the predetermined dimensional characterization, enable the discharge coefficient and the critical cavitation conditions to be determined.
