Turbomachinery Maps: turbocharger_compressor_70
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_70 | 100 | 0.272 | 0.334 | false | false | 65.5 | turbocharger_compressor | Full flow fraction TC 70% speed; very limited boost; engine low-boost condition | 0.334 | 70 | 32 | 0.334 |
| turbocharger_compressor_70 | 110 | 0.299 | 0.288 | false | false | 60.5 | turbocharger_compressor | High flow TC 70% speed; rapidly decreasing efficiency; choke line approach | 0.288 | 70 | 37 | 0.288 |
| turbocharger_compressor_70 | 120 | 0.327 | 0.238 | true | false | 53 | turbocharger_compressor | Choke TC 70% speed; stonewall; very limited range of operation at this speed | 0.238 | 70 | 42 | 0.238 |
