AbstractThis paper presents the verification of a rotorcraft analysis code rFlow3D which based on the Raynolds-Averaged Navier-Stokes equations with the Spalart-Allmaras turbulence model. Two-dimensional flat plate and NACA0012 airfoil are selected as basic verification cases. Validation with a model rotor has also been carried out. In the flat plate case, the velocity profile and the surface skin friction coefficient are confirmed in good agreement with the theory solution and CFL3D results. In the NACA0012 airfoil case, lift and drag coefficients are also in good agreement with the experimental data and CFL3D results. And also, pressure and skin friction coefficients on the wall are obtained the good agreement with CFL3D results. In the model rotor case, the rotor performance is predicted qualitatively in good agreement with the experimental data, but a small offset of rotor torque was observed. Further validation using a finer grid is expected.
