COMPUTATIONAL FLUID DYNAMICS STUDIES

Study of the flow of a fluid in an area or around an object

  • Hydrodynamics calculation
  • Aerodynamics research
  • Solution to the 6 degrees of freedom:  calculation of impact on a hull, acceleration and lift-off, etc.
  • Cavitation prediction and modelling (confirmed by cavitation tunnel tests)
  • Flow analysis and geometry optimization 
  • precise study of the LOADS exerted

     

    In the case of a cargo boat shipping goods, CFD studies allow to know the ship resistance and to analyze the flow. An optimal shape can then be designed to reduce consumption.
