A novel formulation of the lifting-line theory for marine propellers, based on adaptations from the wing lifting-line theory, is reviewed; the formulation is capable of simulating skewed and raked propellers and incorporates the influence of viscosity on thrust and torque through a nonlinear scheme that changes the location of the control points iteratively. Several convergence studies were previously conducted, assessing the different aspects of the numerical tool; the results indicated convergence for propellers of the Kaplan, KCA, and B-Troost series, which generally cannot be satisfactorily simulated by the classical lifting-line alone. However, no validation process was presented, meaning that the solutions obtained had not yet been shown to agree with experimental or numerical data. Thus, four validation cases are presented in this work, evidencing the advantages and limitations of the proposed model.
