| Popis: | This work is devoted to the numerical simulation of the problem about a rotor rotation in a duct in a noninertial reference frame based on the Euler equations. The configuration is a model of a tail rotor of a helicopter. The calculations were carried out using highly accurate EBR schemes on unstructured tetrahedral meshes with the variables determined at the nodes. The numerical results on the aerodynamic forces, as well as the intensity and direction of the acoustic radiation in the far field, are presented and analyzed. |
