Paper presented at the SNAME 26th Offshore Symposium, April 6–7, 2021
Paper Number: SNAME-TOS-2021-22
... for initially setting up a successful model of a self-propelled ship in OpenFOAM. It is demonstrated that, using this framework, results in line with the current state of the art set by leading institutions and commercial solvers can be obtained for the performance of a bulk carrier fitted with an ESD. Two...

Paper Number: SNAME-TOS-2020-024
... An iterative method which couples a vortex-lattice method with a Reynolds-Averaged Navier-Stokes (RANS) method is applied to the prediction of propeller/axisymmetric hull interaction. An open propeller and a ducted propeller are considered. In the coupling procedure, the effective wake...

Paper presented at the SNAME 24th Offshore Symposium, February 20, 2019
Paper Number: SNAME-TOS-2019-019
... In the past, the boundary element method (BEM) has been widely used to predict the potential flow around hydrofoils and propellers. The viscosity, which not only causes friction and reduces the efficiency but also affects the pressure distributions, is considered via an empirical skin friction...

Paper Number: SNAME-TOS-2016-022
... Ducted propellers have been, for a long time, a viable alternative of propulsion; due to their higher efficiency at high thrust coefficients, less sensitivity to the ambient flow, and more robust mechanical layout, than open propellers. Applications of ducted propellers or thrusters can be found...
