Abstract
710,362. Centrifugal. compressors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. July 29, 1952' [Aug. 2, 1951], No. 18298/51. Class 110(1) In a vaneless diffuser at the exit from a centrifugal compressor, the diffuser walls define an equivalent cone angle over any small element of the length of the diffuser passage of not greater divergence than 12 degrees in the median direction of flow. Alternatively, the average equivalent cone angle, measured o v e r the whole length of the diffuser passage, is of not greater divergence than 12 degrees in the median direction of flow. The walls 17 of the diffuser 15 may be frustoconical or, as shown, may be curved. The curvature may be such as to maintain the equivalent cone angle at a value which is substantially constant throughout the length of the diffuser passage. Vanes 16 may be provided beyond the diffuser. In the case of frusto-conical walls, the average equivalent cone angle may be maintained at a predetermined value over a finite length, with a slightly different value over a. succeeding finite length. Specification 693,686 is referred to.
