Turbomachinery Maps: axial_turbine_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 (%) | work coefficient |
|---|---|---|---|---|---|---|---|---|---|---|---|
| axial_turbine_70 | 100 | 0.308 | 0.554 | false | false | 74.5 | axial_turbine | Design-equivalent flow 70% speed; efficiency far below design speed line; high loading losses | 0.554 | 70 | 0.554 |
| axial_turbine_70 | 110 | 0.322 | 0.516 | false | false | 71.5 | axial_turbine | High flow 70% speed axial turbine; efficiency dropping; positive incidence growing; choke near | 0.516 | 70 | 0.516 |
| axial_turbine_70 | 120 | 0.336 | 0.47 | false | false | 66 | axial_turbine | Overload 70% speed axial turbine; choke; severely limited operating range for this speed line | 0.47 | 70 | 0.47 |
