Shipbuilding

From large cruise ships to yachts, from frigates to submarines, many design challenges shall be addressed in the design phases of marine applications. If on the one hand the exterior noise, due to propellers, hull radiation or muffler, has to be limited for discretion or environmental reasons; on the other hand, interior noise is of concern for crew and passengers' comfort.

Actran offers predictive dedicated models addressing both the exterior noise radiation and the interior noise design. Among the many unique features developed to serve the shipbuilding industry are:

• Turbulent Boundary Layer excitation models;
• Aero-acoustic models for propellers' noise prediction;
• support of high-performance computing infrastructures.
