REPORT: Mathematical Modelling and Performance Calculation of Screw Compressors
Weaknesses
Further improvements require dynamic mesh CFD and coupled thermal analysis of rotors and casing. Efficiency : Volumetric and isentropic efficiency
Mechanical efficiency:
Inter-lobe Leaks: Flow across the contact line between rotors. Mechanical efficiency : Inter-lobe Leaks: Flow across the
