ABSTRACT
Increasing demands for efficient screw compressors requires economic and high efficiency rotor designs of screw compressor.Inorder to design a effective rotor rack has to be generated effectively. Numerical and equation adopted in this paper leads to design a effective rotor profile. The solution obtained depends only on the parameters of the rack, pitch, addendum height, dedendum height, rack co ordinates and meshing condition. A suitable procedure for optimization of the screw compressor shape, size, and dimension is described here, which results in the most appropriate design. Compressors thus designed achieve higher delivery rates and better efficiencies than those using traditional approaches.
