Low-aspect ratio appendages for wind-assisted ships

van der Kolk, N.J. (author), Akkerman, I. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author)

Wind propulsion for commercial ships has been identified as a key component in the energy transition for the maritime industry. The sailing hybrid ship will operate with leeway (drift) angles to produce a lateral force known as sideforce, for steady operation under sail. In this paper, experimental results for the sailing performance of ships...

Experiments on a Flettner rotor at critical and supercritical Reynolds numbers

Bordogna, G. (author), Muggiasca, S. (author), Giappino, S. (author), Belloli, M. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author), van 't Veer, A.P. (author)

The Flettner rotor is attracting increasing attention as a viable technology for wind-assisted ship propulsion. Nonetheless, the influence of the Reynolds number on the aerodynamic performance of rotating cylinders is still unclear and under debate. The present study deals with a series of wind-tunnel experiments on a large-scale Flettner...

Hydrodynamics of wind-assisted ship propulsion validation of RANS-CFD methodology

van der Kolk, N.J. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author)

A Reynolds-Averaged Navier Stokes computational fluid dynamics (RANS-CFD) package will be one of the primary tools used during the development of a performance prediction program for Wind-Assisted commercial ships. The modelling challenge presented by large separated flow structures in the wake of the sailing ship points to a conscientious...

Hydrodynamics of wind-assisted ship propulsion verification and validation of RANS methodology

van der Kolk, N.J. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author)

Wind energy as an auxiliary form of propulsion for commercial ships has again become of great interest as a possible response to volatile fuel prices and increasingly stringent environmental regulations. A well-founded performance prediction tool is a key prerequisite for the further development of this promising technology, and with the support...

Validation of a simple aerodynamic model capable to predict the interaction effects occuring between two generic wind propulsion systems

Bordogna, G. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author), Fossati, Fabio Vittorio (author), Belloli, Marco (author)

In recent years wind-assisted propulsion for commercial ships has gained an increasing interest as valuable alternative to reduce fuel pollutant emissions. However, the development of feasible and commercially viable wind propulsion systems to partially (or fully) propel a ship is nowadays hindered by the difficulties of modelling the...
