ABSTRAMI: A series of experiments were conducted to determine the effect of the
number cfblades on the performance characteristics of a mixed-flow compressor vith an
exit blade angle of 90*. The obtained results show that for a compressor with a
rotor diameter on the order of 130 mm, the oDtimum number of blades is about 14.
A reduction in the number of blades results in an increase in the optimum discharge
coefficient A. For example, when the number of blades is reduced from lh to 4, 4
increases from 0.23 to 0.25. This Increase is due to the decrease in the angle of
attack, sinee ~he latter is directly proportional to the number of blades. The pre-
sented curves cmi be used to calculate compressor performance characteristics. Ori

TITLE- Investigation of the effect of vaneless-diffuser width upon compressor
characteristics

TOPIC TAGS. compressor, diffuser, diffuser design
ABSTRAc,r: Sorne results of an experimental investigation of a centrifugal
compressor with an axiradial impeller are reported. Standard characteristics of
the compressor were measured at a constant speed (33000 rpm or 24Z m/sec) and
at different widthe of its vanclega diffuser. Three groups of experiments with
