“…This slipstream contraction geometry is needed for wake modeling in computational fluid dynamics and cannot be neglected for highly loaded propellers since the effective angle of attack of a wing in a propeller slipstream is altered (Veldhuis, 2005). Providing experimental insight of the slipstream contraction will also enable a more realistic wake modeling (Paik et al, 2007b). The current BOS set-up is focused on the slipstream visualization of a single-sting mounted propeller.…”

The Background Oriented Schlieren (BOS) method has been used to qualitatively identify the (variation of) density gradients in the helical structure of a propeller slipstream. The helical structures are identified for two sideslip angles. In contrast to standard BOS correlations between exposures and a reference image, two exposures at a given time interval were cross-correlated. This revealed a more clear description of the propeller slipstream as it determines the variation of the density gradient during this interval. It enhances the visualization of the helical structure of the propeller slipstream. Based on the visualizations of the blade tip vortex trajectories the propeller slipstream contraction can be estimated.

“…Di Felice et al [5] examined the characteristics of propeller wake evolution at different loading conditions. Paik et al [6] investigated the characteristics of the tip vortex and trailing vortex of a propeller. The mechanisms of the evolution of propeller wake in the transition and far fields were researched by Felli et al [7].…”

SummaryIn this study, the wake characteristics of a contra-rotating propeller (CRP) were investigated using a numerical simulation. The numerical simulation was carried out with a Reynolds averaged Navier−Stokes equations solver. The numerical simulations were performed on CRPs in both propeller open water and self-propulsion conditions to investigate their wake evolution characteristics. To study the effect of the rudder on the wake in the selfpropulsion condition, the numerical simulations with and without a rudder were compared. The evolution of the CRP wake was analysed through velocity and vorticity contours on one transverse plane between the forward and aft propellers and two transverse planes located downstream of the CRP. The variations of thrust and torque of the forward and aft propellers during one revolution of the CRP were compared to investigate the interaction between forward and aft propellers and the effect of a rudder.
