description |
Three-dimensional velocity components and six stress
tensor
components
have been obtained experimentally
inside the rotor
wake of an axial
flow
compressor.
The
measurements were made
using a
Hot-wire assembly with a micro-electronic closed system.
Measurements were
taken in
a clean
flow
and
in
a
flow
with
imposed inlet
sine wave pressure
distortion.
The set of wake
data in the distortion flow
mode
,
presented
this thesis
,
are probably the first
reported comprehensive
measurements taken to discern the effect of
inlet
sine wave
pressure
distortion
on rotor wake
behavior.
The mechanism
by
which the loading
variation affects the
wake characteristics radially, frcm the hub to the tip, has been
studied.
A suite of rotor wake analysis programs
has been developed.
The suite
includes
programs dealing
with self-similarity and
preservation
,
decay
and width variation
,
flow thicknesses
and
harmonic decomposition
of the rotor wake.
A mathematical model
for the
,
wake width/decay
characteristics
based on preceeding work
has been improved. The
model uses
the integeral
manentum technigpe. The improvements
allow
the inclusion
of pressure terms
,
turbulence terms
and
the
radial
flow
outside the wake edge
in the final
solution. |
