Abstract EN
Variable inlet guide vane (VIGV) is used to control the mass flow and generate prewhirl in centrifugal compressors.
Due to the tip clearance of the guide vanes and the defect of the traditional guide vane profiles, the mass flow regulation of VIGV is limited, resulting in a large waste of compressed gas.
Two kinds of inlet flow channels were proposed to eliminate the influence of tip clearance.
These structures were numerically investigated at different setting angles.
The results show that the improved channels not only expand the range of mass flow regulation, but also reduce the power and increase the efficiency of the compressor.
Ten kinds of guide vane profiles, including different thickness distribution, camber line profile, were selected to compare with the original one and with each other.
In the premise of ensuring the performance of compressor, the best guide vane profile was selected.
The results show that reducing the guide vane thickness, increasing the guide vane camber angle, and increasing the distance between the maximum camber position and the leading edge of guide vane can help expand the range of mass flow regulation.
The achievement of this research can effectively improve the flow regulation ability of VIGV and the performance of compressor.
