DIFFUSER HAVING MULTIPLE ROWS OF DIFFUSER VANES WITH DIFFERENT SOLIDITY
摘要
A diffuser for a compressor includes an annular diffuser passageway defined by a hub wall and a shroud wall of a housing of the compressor. The annular diffuser passageway may be fluidly coupled with a centrifugal impeller configured to rotate with a rotary shaft of the compressor about a center axis. The diffuser may also include a plurality of low solidity diffuser vanes extending into the annular diffuser passageway from the hub wall or the shroud wall and arranged annularly about the center axis. The diffuser may further include a plurality of high solidity diffuser vanes disposed radially outward from the plurality of low solidity diffuser vanes and extending into the annular diffuser passageway from the hub wall or the shroud wall and arranged annularly about the center axis.
