Turbomachinery Maps: centrifugal_compressor_90
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_90 | 100 | 0.38 | 0.385 | false | false | 80.5 | centrifugal_compressor | Full flow fraction 90% speed; head substantially below 100% | 0.385 | 90 | 37 | 0.385 |
| centrifugal_compressor_90 | 110 | 0.418 | 0.33 | false | false | 74.5 | centrifugal_compressor | High flow 90% speed; efficiency declining | 0.33 | 90 | 42 | 0.33 |
| centrifugal_compressor_90 | 40 | 0.152 | 0.568 | false | true | 51 | centrifugal_compressor | Surge at 90% speed; surge boundary moves to lower phi | 0.568 | 90 | -12 | 0.568 |
