Hydrodynamic optimisation of a zero emission battery-driven catamaran

Hydrodynamic optimisation of a zero emission battery-driven catamaran

By Yan Xing-Kaeding, Hamburgische Schiffbau-Versuchsanstalt The optimisation of battery-powered ships for efficient, emission-free coastal passenger transport brings to the forefront a significant emphasis on hydrodynamic design. This intricate process, crucial for minimising resistance and energy consumption, takes on heightened importance due to the unique requirements of these vessels. Operating on short-distance routes and focusing on […]

Efficient CFD simulations for speed and delivered power in waves at full scale

By Michal Orych, managing director, FLOWTECH Int. AB, Martin Kjellberg, RISE Research Institutes of Sweden/SSPA, and Lars Larsson, Chalmers University of Technology Computational fluid dynamics (CFD) is presently an accepted tool for predicting calm water resistance and power at model scale. The status of CFD for these applications is well covered by the International Workshops […]
