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 …

X-ray diagnostics have the potential for making quantitative measurements in many
flowfields where optical diagnostics are challenging, especially multiphase flows. In the past …

The fuel-ambient mixture in vaporized fuel jets produced by liquid sprays is fundamental to
the performance and operation of engines. Unfortunately, experimental difficulties limit the …

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 …

In recent years, X-ray radiography has been used to probe the internal structure of dense
sprays with microsecond time resolution and a spatial resolution of 15 µm even in high …

This paper implements a coupled approach to integrate the internal nozzle flow and the
ensuing fuel spray using a Volume-of-Fluid (VOF) method in the finite-volume framework. A …

Abstract Traditional Discrete Particle Methods (DPM) such as the Euler–Lagrange
approaches for modeling atomization, even if widely used in technical literature, are not …

Measurements of droplet size in optically-thick, non-evaporating, shear-driven sprays have
been made using ultra-small angle x-ray scattering (USAXS). The sprays are produced by …

Numerical modeling of high-pressure liquid fuel injection remains a challenge in various
applications. Indeed, experimental observations have shown that injected liquid fuel jet …

This work evaluates the performance of the Σ-Y Eulerian atomization model at reproducing
the internal structure of a diesel spray in the near-field. In the study, three different …
