Mathematical Modelling And Performance Calculation | Screw Compressors-
For many gases (especially refrigerants like R134a or hydrocarbons), ideal gas law fails. A real gas equation like or NIST REFPROP correlations is used:
Modern modelling also looks at . As the discharge port opens, there is often a "pressure mismatch" (over-compression or under-compression). This creates shock waves that lead to noise and vibration. Advanced models use CFD (Computational Fluid Dynamics) to optimize the shape of the discharge port to minimize these losses. Conclusion For many gases (especially refrigerants like R134a or
Applying the first law of thermodynamics to a chamber of volume ( V(\theta) ) (function of male rotor rotation angle ( \theta )): For many gases (especially refrigerants like R134a or
