    Computational aerodynamics of hovering helicopter rotors by Nik Mohd., Nik Ahmad Ridhwan, Barakos, George N.

    Published 2012
    “…The benefits and differences between simple, momentum-based source-sink models and truncated vortex-tube far-field boundary conditions on the rotor flowfield modelling, and the convergence of the numerical solution are investigated and presented. Helicopter rotors in axial flight are simulated using the Helicopter Multi-block (HMB2) solver of the Liverpool University for a range of rotor tip speeds and collective pitch settings. …”
