The positive displacement twin-screw compressor is used to compress gases to modest pressures. Internal leakage is a fundamental issue with screw compressors. The design and performance are impacted by the phenomenon of leakages across various clearances. The experimental processes are costly and time-consuming to manufacture screw compressor. The performance of various tooth profiles of screw compressor can be determine by utilising CFD. The aim of study is to develop screw compressor profiles in solid modelling software and numerical analysis in CFD. The change in the flow rate, clearance, and tooth profile and by considering other parameter, like pressure velocity and temperature, the clearance between the male-female and casing can be adjusted and hence the scope of improvement considering the actual phenomena taking place within the screw compressor. By modifying the input parameter the losses between the internal leakages and the functional issues with the screw compressor can be minimize

Rotary twin screw compressor are widely used in the refrigeration, gas processing and energy industries and their application are diverse. Flow rate, pressure, temperature and working fluid are all factors to consider for good screw compressor. Twin-screw compressor are generally simple and small in construction with improved dependability, due to a lower moving components. They are primarily classed as oil-free and oil-flooded, and owing to their low cost, they may be used to compress helium and other gases in addition to air. Twin screw compressor are replacing reciprocating compressor due to improved profile design. Because of technological advancements and continues improvement the industry’s necessity for exact performance projections has become a reality advances in the current analytical and simulation tools where appropriately can be proven by experimental investigation.
