The topic of this work is the numerical simulation of a problem of interest in the field of offshore technology, namely the inviscid flow around four free–surface piercing cylinders in waves. Three different angles of the incoming wave front are considered in order to investigate the variation of the resulting global and local loads on the four bodies. The rotation of the cylinders configuration with respect to the wave front has been made easy and efficient by the use of a chimera method for the generation of the computational mesh. The free–surface has been simulated by an one–phase level set approach.

The Way

Position initiation error shows great influence on new EFP. It not only causes the way of crushed liner by detonation wave at initial phase, but also influences wave front to show asymmetric. Finally it influences detonation wave collision effect to make penetrator slope. The influence of position initiation error on new EFP was studied in numerical simulation. As increase of position initiation error, tilt trend shows faster. For different length of charge, position initiation error shows different collision effect. Position initiation error shows greater influence with smaller length charge than larger.
