The
mathematical
model
used
in
this
simulation
is
the
two-phase
interface-tracking
Eulerian
model.
A
phase
fraction
describes
the
state
at
all
points
in
the
jet:
0
corresponding
to
air;
1
to
the
Diesel
fuel.
Turbulence
has
an
important
effect
on
the
early
breakup
process
and
is
modelled
by
LES
using
a
1-equation
subgrid
model.
