Physical properties of the model

  • Steady-state, compressible gas flow
  • Ideal gas:
    • Medium: Air
    • Viscosity: $ \color{white} \mu = 1.831 \cdot 10^{-5}$ $ \color{white} Pa \cdot s$ (Sutherland’s formula)
    • Specific heat capacity: $ \color{white} C_p = 1004.4$ $ \color{white} J \cdot kg^{-1} \cdot K^{-1}$
    • Prandtl number: $ \color{white} Pr = 0.7$
    • Thermal conductivity: $ \color{white} \lambda = 2.61 \cdot 10^{-2 }$ $ \color{white} W \cdot m^{-1} \cdot K^{-1} $
  • Wheel speed: $ \color{white} 100 000$ $ \color{white} RPM$
