The governing equations solved here are the conservation of mass and the conservation of momentum (Navier-Stokes equations), taken in a frame of reference moving with the turbine:
- Conservation of Mass:

Boundary Conditions
The boundary conditions are:
- Inlet (far-field): constant velocity in the x-direction of 10m/s, with turbulent intensity of 5% and turbulent viscosity ratio of 1.
- Outlet (far-field): absolute pressure of 101325 Pa, or 1 atm, with same turbulent parameters as above.
- Blades: wall, so no velocity. (No-slip condition).
