Design the following air-operated axial turbine stage (mean radius values). That is, create a velocity triangle, and calculate the load factor, recoil, and output.
and find the nozzle outlet Mach number. Assuming a polytropic efficiency of 90%, find the short-exit voltage force. However, the specific heat of the ideal gas air is
Assume that CP = 1.148 kJ/kgK, the specific heat ratio is constant at 1.333, and the gas constant is 0.287 kJ/kgK.
- Flow = 20kg/s, pre-inlet temperature (T01) = 1100K, total temperature drop (T01 – T03)=145K, inlet voltage (P01)=4bar
- Rotor blade speed (U) = 340m/s, single entrance absolute angle (a1)
)=0o
, the absolute angle of the single outlet (a3
)=10o
, flow coefficient (f) = 0.8 (constant, i.e. axial velocity is
determined)
