Simulations of a canonical helical vortex systems are utilized to explore the influence of grid resolutions on vortex wake breakdown. A consistent-strength helical vortex system will be created by an actuator “surface” representation of a rotor. Normal and oblique traversal of grid boundaries by waves and vortices of selected intensities will be analyzed to study the influence on vortex wake break down. The ensemble of simulations includes uniform overset and stretched background grids. The preservation of flow features as the wake field traverses resolution boundaries is described. Recommendations for grid configurations that best preserve the flow field are detailed.
