N2 - A computational study is conducted for coaxial rotor hubs with a sail fairing to characterize its downstream wake and surface forces. The flow conditions and grids are based on experimental tests performed at the Penn State Applied Research Lab (ARL) Water Tunnel at appropriate Reynolds numbers. Grid development for the rotor hubs and sail fairing is done using Pointwise v18.0R1 and Chimera Grid Tools. Simulations are performed using NASA's OVERFLOW 2.4b Reynolds Averaged Navier-Stokes solver. The drag forces on the rotor hubs are computed and compared to previous computational studies and experimental results. The drag forces are similar to previous computational studies but still do not match experimental results. The streamwise, spanwise, and vertical velocity components of the wake have been visualized, analyzed, and compared to experimental results. Further work is needed to analyze frequency content and Reynolds stresses.
