Operation features of the diametrical disc fan at low pressures

Thermophysics and Aeromechanics Aims and scope

Abstract

Operation of the diametrical disc fan was studied experimentally at low (5–50 torr) pressures in air. The effect of a drastic decrease in volumetric flow rate of the fan was revealed at pressures below 40 torr (flow rate crisis), what does not correlate with published data. The critical value of dimensionless parameter corresponding to flow transformation and formation of a closed flow inside a fan was determined and proved experimentally.
