Turbomachinery Maps: turbocharger_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 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| turbocharger_compressor_80 | 100 | 0.311 | 0.378 | false | false | 72.5 | turbocharger_compressor | Full flow fraction TC 80% speed; psi much below 100% line; low boost pressure at engine mid speed | 0.378 | 80 | 35 | 0.378 |
| turbocharger_compressor_80 | 110 | 0.342 | 0.327 | false | false | 67 | turbocharger_compressor | High flow TC 80% speed; efficiency drops significantly; choke near | 0.327 | 80 | 40 | 0.327 |
| turbocharger_compressor_80 | 120 | 0.373 | 0.27 | true | false | 59.5 | turbocharger_compressor | Choke TC 80% speed; stonewall; low speed means low absolute mass flow limit | 0.27 | 80 | 45 | 0.27 |
