Slam induced loads on bow-flared sections with various roll angles

• The 2D water entry of a bow-flared section is studied using an explicit finite element code.
• The modelling adopts a multi-material Arbitrary Lagrangian–Eulerian and a penalty coupling methods.
• The simulated vertical slamming force and pressure histories are compared with experiments.
• The effects of the roll angle on the slamming load are studied.

The two-dimensional water entry of a bow-flared section with different roll angles is studied by using an explicit finite element code. The modelling technique of the fluid–structure interaction adopts a multi-material Arbitrary Lagrangian–Eulerian formulation and a penalty coupling method. The simulated vertical slamming force and pressure histories are compared with experiments and other numerical calculations. The effects of the roll angle on the slamming load are studied through simulations for a bow-flare section with different roll angles.
