摘要：

The problem of shrouded rotor rotation is numerically solved basing on the Navier-Stokes equations in a noninertial coordinate system. The configuration considered is a model helicopter tail rotor. The calculations are performed using edge-based reconstruction (EBR) schemes on unstructured tetrahedral grids with the variables determined at gridpoints. The numerical results on the aerodynamic forces and the acoustic radiation intensity and direction in the far field are presented and analyzed.
