Modelling of a air compressor

I am trying to model a screw compressor in matlab/simulink. the parameters which i know are just input temperature, pressure and mass flow rate. I need to model a compressor with a desired output pressure of 80bar. Can anyone provide me with a related information on how to model the compressor. All leads will be valued. Thanks in advance

m ledu bro.... first of all, compressor block open chesi help loki vellu. Akkada related emperical correlations untaayi. Avi follow avuthu, corrected mass flow and shaft speed ivanni nuvve calculate chesi input ivvaali. Based on the output pressure and temperature, oka error controller petti, speed of compressor ni thakkuva cheyi. You can also use 1D look up table bro.
