要約

An approach to numerical calculation of the aerodynamic and acoustic characteristics of a realistic rotor is presented. The numerical calculation of the aerodynamic parameters is based on a high-order implicit scheme applicable to arbitrary unstructured meshes. The sound field is calculated using the Ffowcs Williams−Hawkings approach. To decrease the calculation time, a parallel version of the aerodynamic solver is used, which is based on the message passing interface technology. The applicability of the approach and the corresponding software are illustrated through the problem of flow around a six-blade aviation propeller and include validation of the solver by comparing the numerical results with the experimental data for drag and thrust, scalability tests for up to 1024 processor cores, and study of the influence of the time step size on the convergence rate to the stationary solution. The calculation of the acoustic field is verified on the basis of an exact solution of the linear approximation.
