NEW JIP ON FOIL DESIGN

Hydrofoil technology has been known for decades and mostly focused on the performance of hydrofoils in steady state conditions. However, there is still work to be done in terms of dynamic response of hydrofoils in unsteady conditions, particularly in the eventual presence of cavitation and/or ventilation. This JIP aims at achieving advanced knowledge to assist

面对气候变化的推船设计

Pushboat design considerations facing climate change Pushboat operators, especially those operating on the rivers, face the transition to zero emission propulsion in combination with longer periods of low water. This results in conflicting design specifications. By combining different disciplines, MARIN is extending the scope of its design support to cope with this challenge. Autonomy

变工况下潜艇流体力学

AuthorsToxopeus, S., Kerkvliet, M., Vogels, R., Quadvlieg, F., Nienhuisz, B. Conference/JournalConference on Computational Methods in Marine Engineering (Marine 2021) DateJun 2, 2021 Traditionally, submarine hydrodynamic design has focussed mainly on requirements regarding operational range, powering performance and manoeuvring ability for deeply submerged conditions. To improve the effectiveness of the boat, attention is also paid to

Farwind: an energising design concept

Farwind has led to the development of a multihull that is fully propelled by the wind. And as it sails, water turbines underneath are powered to generate electricity. The harvested energy is stored on board and brought to shore. Farwind design concept At societal level, such a project could make a big impact
