Numeric Simulation

We predict the performances of naval platforms

Thanks to the progress made in computational fluid dynamics, the hydrodynamic performances of most naval platforms can now be simulated. The expertise of SIREHNA’s engineers makes them able to fully exploit the potential of these methods.

Qualified and industrialized methods are used to predict the performances of various marine systems, such as ships, submarines, propellers, tidal turbines… SIREHNA also prepares and validates new methods and tools to answer more complex problems.

Some of the problematics SIREHNA deals with are:

  • Ship resistance
  • Self-propulsion
  • Seakeeping
  • Maneuverability
  • Cavitation
  • Vehicles launch and recovery,  marine operations
  • Aerodynamics
  • Turbulence
  • Water waves
  • Wakes
  • Hydro-acoustics
