Turbomachinery Maps: axial_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 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| axial_compressor_70 | 100 | 0.322 | 0.215 | false | false | 70.5 | axial_compressor | Full flow fraction 70% speed; very low pressure rise output | 0.215 | 70 | 26 | 0.215 |
| axial_compressor_70 | 110 | 0.329 | 0.19 | true | false | 65 | axial_compressor | Choke 70% speed; stonewall at reduced tip Mach number | 0.19 | 70 | 32 | 0.19 |
| axial_compressor_70 | 50 | 0.245 | 0.242 | false | true | 54 | axial_compressor | Surge at 70% speed; very limited stable range; axial blade operates highly off design | 0.242 | 70 | -22 | 0.242 |
