ABSTRACT:
An improved diffuser has a first row of low solidity vanes followed by a second row of low solidity vanes. The chord of the second row of vanes is greater than the chord of the first row. The second row is located radially outward from the trailing edges of the first row and circumferentially displaced to lie in the shadow of the first vane.
