Swirl Recovery Vanes for Propeller Propulsion Systems: An Aerodynamic and Aeroacoustic Investigation by Lattice Boltzmann Method

An unexploited rotational momentum, i.e. swirl, is present in the slipstream of propellers. Stationary vanes, called swirl recovery vanes (SRVs), have been proven to be effective in increasing the propulsive efficiency of propellers. There is however no conclusive answer in literature on the noise effect of SRVs. Additionally, as the propeller...
