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

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. (C) 2013 Elsevier Ltd. All rights reserved.
