Fluid dynamics is one of the long-established areas of CETENA’s activities. Know how has been built in the frame of international cooperations, EU projects, active participation in the Cooperative Research Ship.

Computational fluid dynamics (CFD) is largely used for the assessment of ship and propeller design and the analysis of a number of ship operation aspects, such as propulsion, seakeeping, manoeuvring in calm water and waves, ship aerodynamics. Different fluid dynamics simulation software - in-house , commercial and open source – are used depending on the issue to be investigated and the required level of accuracy.

CETENA’s expertise in fluid dynamics comes from both research and a close relationship with the industry, the latter driving R&D towards the development of methods and tools to be effectively used to improve design and solve practical problems. As in other areas of CETENA’s activities, a long standing relationship with the Italian Navy is a matter of pride and has contributed to the development of know how in the naval area.
