Optimisation of screw compressors.

Summary

A suitable procedure for optimization of the screw compressor shape, size, dimensions and operating parameters is described in this article, which results in the most appropriate design for a given compressor application and fluid. It is based on a rack generation algorithm for rotor profile combined with a numerical model of the compressor fluid flow and thermodynamic processes. Some optimization issues of the rotor profile and compressor parts are discussed, using 5/6 screw compressor rotors to present the results. It is shown that the optimum rotor profile, compressor speed, oil flow rate and temperature may significantly differ when compressing different gases or vapours or if working in the oil-free or oil-flooded mode of operation.
