Gasoline direct injection (GDI) sprays are complex multiphase flows. When compared to
multi-hole diesel sprays, the plumes are closely spaced, and the sprays are more likely to …

A computational study was performed to investigate the influence of transient needle motion
on gasoline direct injection (GDI) internal nozzle flow and near-field sprays. Simulations …

This work involves modeling internal and near-nozzle flows of a gasoline direct injection
(GDI) nozzle. The Engine Combustion Network (ECN) Spray G condition has been …

Internal flow is closely related to energy consumption and emissions because of its
dominant role in the atomization process. The intricate three-phase flow patterns in an orifice …

An extensive numerical study of two-phase flow inside the nozzle holes and the issuing jets
for a multi-hole direct injection gasoline injector is presented. The injector geometry is …

In an era where engine design has been influenced by the interest in emissions reduction,
the use of gasoline direct injection systems has proven to be an effective means to approach …

In order to simultaneously study the differences in transient flow characteristics within each
nozzle hole of an asymmetric multi-hole diesel injector used in off-road machinery, a three …

The objective of this study is to unravel the driving mechanisms behind the plume expansion
and fluctuations in the near-field. A collaborative experimental and numerical study was …

A computational approach to predict external spray characteristics for flashing and cavitating
nozzles was presented and validated. It is developed as a fully Eulerian and compressible …

Performance of a gasoline direct injection engine significantly depends on the fuel injection
phenomenon. It has been shown that variation in the fuel thermo-physical properties and in …
