Effect of the air density on the evolution and mixing properties of a GDI swirled spray 2001-24-0048
A swirl injector for GDI application was used to inject an
iso-octane spray in a quiescent chamber, to study the effect of the
air density on the spray behavior.
Stroboscopic images are recorded at different delays from the
injection trigger to study the spray shape and structure. The
temporal evolution of different spray parameters, length, width,
angle, volume, instantaneous global air-fuel ratio, is calculated
from the images. The effect of the increasing air density is to
shorten the time and length scale of the spray evolution.
