Numerical simulation of water entry of different arbitrary bow sections

Water impact phenomenon of general bow section is a critical event for planning hulls. in this paper,the water entry of several arbitrary bow sections is investigated. for this purpose,arbitrary bow shapes which are introduced by lewis form approximation are considered. in order to obtain pressure distribution and free surface profile,volume of fluid (vof) method coupled with finite volume method (fvm) are utilized in ansys-cfx solver. pressure distribution,free surface,and evolution of intersection point on bow sections are presented,while secondary water impact is demonstrated. comparison of the obtained results against previously published works shows good agreement. © 2014 aname publication. all rights reserved.
