Assessment of Numerical Captive Model Tests for Underwater Vehicles: The DARPA SUB-OFF Test Case
Journal of Marine Science and Engineering, 2023 During the early design stage of an underwater vehicle, the correct assessment of its manoeuvrability is a crucial task. Conducting experimental tests still has high costs, especially when dealing with small vehicles characterized by low available budget.

Erratum to: Effect of fibrils on curvature-and rotation-induced hydrodynamic stability [PDF]
Acta Mechanica, 2015 Unfortunately, the calculation of the theoretical viscosity was incorrect in the original article. This error affects Figs. 6 and 10 and four text passages where these figures are discussed. The main result of the paper, i.e. that the experiments show that fibrils affect the instability less than what would be expected from viscometry but more than ...

Weakly Nonlinear Hydrodynamic Stability of the Thin Newtonian Fluid Flowing on a Rotating Circular Disk [PDF]
Mathematical Problems in Engineering, 2009 The main object of this paper is to study the weakly nonlinear hydrodynamic stability of the thin Newtonian fluid flowing on a rotating circular disk. A long‐wave perturbation method is used to derive the nonlinear evolution equation for the film flow.
