Computational models are unavoidably affected by epistemic uncertainty.rnIndeed, specific assumptions define the structure of turbulence closures in the RANS model, limiting the general credibility of the model.rnWe suggest a modification of the Eigenspace Perturbation Method to increase the depth of the uncertainty analysis in investigating the aerodynamic performance of two tandem propellers.
