This problem uses a mesh that is generated by distorting cells downstream of the propeller. The result is a mesh with over
non-orthogonality and severe skewness. The problem incorporates centrifugal and Coriolis terms to simulate the spinning of the propeller and uses RANS
turbulence modelling. The numerics are tuned to resolve the pressure vortices from the propeller tips using non-orthogonal and skewness correction.
