Turbomachinery Maps: axial_turbine_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 (%) | work coefficient |
|---|---|---|---|---|---|---|---|---|---|---|---|
| axial_turbine_90 | 100 | 0.396 | 0.718 | false | false | 88 | axial_turbine | Design-equivalent flow 90% speed; slightly reduced efficiency; good off-design point | 0.718 | 90 | 0.718 |
| axial_turbine_90 | 110 | 0.414 | 0.669 | false | false | 85.5 | axial_turbine | High flow 90% speed axial turbine; efficiency declining; choke onset at throat | 0.669 | 90 | 0.669 |
| axial_turbine_90 | 120 | 0.432 | 0.61 | false | false | 80.5 | axial_turbine | Overload 90% speed axial turbine; choke; mass flow limited by throat area; significant efficiency loss | 0.61 | 90 | 0.61 |
