Sprays are among the most intellectually challenging and practically important topics in fluid
mechanics. This paper reviews needs, milestones, challenges, and a broad array of …

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 …

Cavitation plays an important role in fuel injection systems. It alters the nozzle's internal flow
structure and discharge coefficient, and also contributes to injector wear. Quantitatively …

The internal details of fuel injectors have a profound impact on the emissions from gasoline
direct injection engines. However, the impact of injector design features is not currently …

A computational and experimental study was performed to characterize the flow within a
gasoline injector and the ensuing sprays. The computations included the effects of …

In this article, a fully compressible two-phase flow model combined with a multi-component
real-fluid phase equilibrium solver is proposed for cavitation modeling. The model is able to …

The generation and development of cavitation in the flow channel inside the injector ball
valve had been characterized using a high-speed visualization system. The flow field …

The multiphase flow inside a diesel injection nozzle is imaged using synchrotron X-rays from
the Advanced Photon Source at Argonne National Laboratory. Through acquisitions …

Hydraulic flip is a common phenomenon that occurs in a short injector nozzle with a
contraction flow which results in a separation flow without a wall reattachment. This …
