Turbomachinery Maps: centrifugal_compressor_80
Turbomachinery performance maps — compressor, turbine, fan, pump, and turbocharger characteristic curves showing efficiency, pressure ratio, head coefficient, and surge/choke boundaries at various speeds and flow rates
| machine speed | flow pct | flow coefficient | head coefficient | is choke point | is surge point | isentropic efficiency pct (%) | machine type | notes | power coefficient | speed pct (%) | surge margin pct (%) | work coefficient |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| centrifugal_compressor_80 | 100 | 0.34 | 0.352 | false | false | 74.5 | centrifugal_compressor | Full flow fraction 80% speed; low pressure ratio vs design | 0.352 | 80 | 34 | 0.352 |
| centrifugal_compressor_80 | 40 | 0.136 | 0.51 | false | true | 45.5 | centrifugal_compressor | Surge at 80% speed; lower tip speed reduces choke-surge range | 0.51 | 80 | -18 | 0.51 |
| centrifugal_compressor_80 | 50 | 0.17 | 0.5 | false | false | 55 | centrifugal_compressor | Low flow 80% speed; near surge boundary | 0.5 | 80 | -7 | 0.5 |
