Abstract
Numerical studies of the tip vortex structure from a hovering rotor with and without various spoilers are presented. A general multizone unsteady three-dimensional Navier-Stokes solver is developed to determine the flowfield. A scheme that is fifth-order accurate in space and first-order accurate in time is used to improve the capturing of the tip vortex. Velocity data from the core of the vortex is studied at various planes behind the blade trailing edge. Computations of this velocity data for a clean rotor are first compared with experimental results obtained for the same rotor test case. Three different trailing edge spoiler configurations are then investigated to see if the tip vortex structure can be favorably altered.
