The influence of blade profile shape of inlet guide vane on performance map of centrifugal compressor stage
The object of the study is a centrifugal compressor stage with an inlet guide vane. The performance map of the stage are investigated in the modes of combined regulation by changing the rotor speed and changing the swirl of the flow in front of the impeller by turning the blades of the inlet guide...

| description | The object of the study is a centrifugal compressor stage with an inlet guide vane. The performance
map of the stage are investigated in the modes of combined regulation by changing the rotor speed
and changing the swirl of the flow in front of the impeller by turning the blades of the inlet guide vane.
Two variants of the design of the profile of the blades of the inlet guide vane are considered and the
method of turning the blades by performance map. As a result of the study, it is found that a profile
with a fixed inlet part at large swept angles has a lower loss coefficient, which contributes to an increase
in the efficiency of the stage. The effect of regulation to achieve the set point in terms of pressure and
flow for the re-profile stage is achieved at lower speeds |
