Screw Compressors- | Mathematical Modelling And Performance Calculation

Efficiency is largely dictated by what doesn't get compressed. Leakage paths include:

$$ \eta_is = 20.1 / 23.65 = 0.85 \text (85%) $$ Efficiency is largely dictated by what doesn't get

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 Efficiency is largely dictated by what doesn't get
