Turbomachinery Maps: radial_turbine_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 (%) | work coefficient |
|---|---|---|---|---|---|---|---|---|---|---|---|
| radial_turbine_80 | 100 | 0.38 | 0.632 | false | false | 80 | radial_turbine | Design-equivalent flow 80% speed; notable efficiency gap from 100% speed line | 0.632 | 80 | 0.632 |
| radial_turbine_80 | 110 | 0.418 | 0.598 | false | false | 77.5 | radial_turbine | High flow 80% speed radial turbine; efficiency declining; off-design incidence dominant | 0.598 | 80 | 0.598 |
| radial_turbine_80 | 120 | 0.456 | 0.558 | false | false | 73 | radial_turbine | Overload 80% speed radial turbine; significant efficiency penalty | 0.558 | 80 | 0.558 |
