| dc.description.abstract | A numerical model for partial alignment of propeller vortex wakes with the flow is investigated. A lifting line representation of the propeller blades is used combined with the vortex lattice discretization method. The model takes into account radial contraction and axial variation of the pitch of the trailing vortices. The convergence of the iterative pitch alignment procedure and the influence of the number of vortex elements is studied in the case of an optimum moderately loaded propeller. The effects of axial variation of pitch and contraction are investigated for the same optimum circulation distribution case. The model is applied to the vortex wake of propeller DTRC 4119 and results are compared with experimental data. | por |
