Description
A rotorcraft flow solver, rFlow3D, has been extended for ducted rotors. A circular grid topology has been implemented to enable a body grid solver to compute the duct shape. A background cylindrical grid is adopted for fine grid resolution of the clearance between the blade tip and the duct. Octree based interpolation processing is utilized for a fast interpolation between the body grid and the background cylindrical grid. The validation about the new adopted grid and the prediction accuracy of the ducted rotor performance is carried out based on an experiment of ducted rotor at Osaka University. A hovering rotor on a background cartesian and a cylindrical grid are simulated and compared reasonably well. The predicted ducted rotor performance is shown a good agreement with the experimental data.
