Shipbuilding & naval

The K-EPSILON solution provides global aerodynamics and hydrodynamics, powerful tools and customized studies to reduce the cost and accelerate the development of new classes of ship in their new challenges:

- Simulating turbulent flow around ship hulls
- Simulating behavior in waves for seakeeping and slamming
- Modeling of cavitating propellers
- Addressing tank sloshing problems

Computational fluid dynamics (CFD) is a powerful marine design tool capable of accurately predicting complex flow phenomena. A key advantage is its ability to model the complex and arbitrary geometries that are typical of real-world equipment.

Today, K-EPSILON's services help our customers to accurately predict some of the most difficult marine engineering problems. Simulation provides engineers with the ability to accurately determine the performance of design concepts, reducing the need for tank test and the building of prototypes. This makes it possible to evaluate many more designs, resulting in a substantial improvement in performance. At the same time, the lower cost and shorter lead-times of simulation provide faster time to market and reduced development costs. When you also consider that CFD simulation provides more design data than tank test, you end up with an unbeatable proposition for its use in marine research and design.
