Unlike in the case of high Reynolds number airfoil, selecting a turbulent closure model for the low Reynolds number airfoil is still a challenge. A turbulent model used for high Reynolds number airfoil is not necessarily suitable for low Reynolds number a... see more

Purpose. The article is aimed to: generate 3D models of the screw-propellers under study, as well as the calculation box; carry out a series of numerical experiments to verify the obtained results with the corresponding results of the model experiments; s... see more

An unsteady 3D surface panel method has been developed to predict hydrodynamic load fluctuations on an ice class propeller induced by continuous variation of proximity to an ice block. The low order, time domain, combined doublet and source panel method a... see more

This work presents an experimental study of the effect of an installed propeller slipstream on a wing boundary layer. The main objective was to analyse through wind tunnel experiments the effect of the propeller slipstream on the wing boundary layer chara... see more

The understanding of the performance of a propeller in realistic operative conditions is nowadays a key issue for improving design techniques, guaranteeing safety and continuity of operation at sea, and reducing maintenance costs. In this paper, a summary... see more

This paper presents an hardware-in-the-loop (HIL) simulation system tool to test and validate an autonomous free running model system for ship hydrodynamic studies with a view to verification of the code, the control logic and system peripherals. The comp... see more

The aim of the present work is to define the propeller correction that must be machined in the pinion of a meshed contact in order to compensate the effects of the displacement of the shaft due to its flexo-torsion and the effects of the displacement of t... see more

In the present study, the effect of the duct angle and propeller location on the hydrodynamic characteristics of the ducted propeller using Reynolds-Averaged Navier Stokes (RANS) method is reported. A Kaplan type propeller is selected with a 19A duct. The... see more

The aim of the present work is to define the propeller correction that must be machined in the pinion of a meshed contact in order to compensate the effects of the displacement of the shaft due to its flexo-torsion and the effects of the displacement of t... see more
