EFFECT OF THE NUMBER OF ROTOR BLADES ON THE CHARACTERISTICS OF AN AXIRADIAL COMPRESSOR,
Abstract
A series of experiments were conducted to determine the effect of the number of blades on the performance characteristics of a mixed-flow compressor with an exit blade angle of 90 degrees. The obtained results show that for a compressor with a rotor diameter on the order of 130 mm, the optimum number of blades is about 14. A reduction in the number of blades results in an increase in the optimum discharge coefficient phi. For example, when the number of blades is reduced from 14 to 4, phi increases from 0.23 to 0.25. This increase is due to the decrease in the angle of attack, since the latter is directly proportional to the number of blades. The presented curves can be used to calculate compressor performance characteristics.
