Performance analysis of an oil-injected screw compressor and its application.

Type of article: Article, IJR article

Summary

Flow and heat-transfer characteristics required for computer simulation of screw compressors are experimentally obtained and used in performance prediction, where the working medium is air. The heat-transfer coefficient is determined from the experimental relation between the volumetric efficiency and the inlet temperature. Flow coefficients are obtained from the efficiency-clearance curves. Applying those coefficients to the performance simulation, good agreement is obtained between the tested and calculated performance of three different prototype air compressors. A new rotor profile aimed at higher performance is designed based on the simulation results. The tested performance of the new profile compressor is much higher than that of a conventional compressor. The new profile compressor has been applied to a commercial series of packaged-air screw compressors.
