The paper presents an extension to ducted rotors of the nonlinear actuator disk theory of
Conway (J. Fluid Mech., vol. 365, 1998, pp. 235–267) and it is exact for incompressible …

This paper completes the work presented in the companion paper [Bontempo et al., Appl.
Ocean Res., 58 (2016) 322–330] by presenting the investigation of the flow around a …

The paper presents a generalized semi-analytical actuator disk model as applied to the
analysis of the flow around ducted propellers at different operating conditions. The model …

Although there have been important developments in marine propellers since their first use
in 1850, the main concept has been conserved. Parallel to the developments in the …

The use of a duct around the propeller aims to increase the propulsive efficiency by means
of accelerating the inflow to the propeller (accelerating duct, kort nozzle), to decrease the …

En el presente estudio se reporta el efecto del ángulo de ducto y la ubicación de la hélice
sobre las características hidrodinámicas de la hélice con ducto, usando el método RANS …

In this study, CFD methods are used to solve the complex flow around a CPP propeller with
ducts. It is aimed to investigate the performance differences between ducted and non-duct …

In the present study, the aerodynamic performance of the ducted fan is investigated using
the surface vorticity method and the lifting line theory. In previous research, to consider the …

This paper presents the numerical simulation of the 3-seater hovercraft's ducted propeller
performance with Ansys CFX. This 3-seater hovercraft is the first one which was …
