... ABSTRACT In this paper, numerical simulations of diffracted wave around bottommounted circular cylinder are presented using volume-of-fluid (VOF) method. Unsteady incompressible Navier-Stokes equations are solved based on finite volume method (FVM) with collocated variable arrangement. SIMPLE...

... developed to Navier-Stokes equation and validated by the comparison with published results. Using the developed numerical codes, the nonlinear interaction between structures and waves are discussed. It is found that complicated interactions between diffracted waves generated by physical circumstances...

... deformation due to the structures. Recently, the theoretical treatment has been extended to consider the nonlinear effects (e.g., Ghalayini and Willams, 1989, 1991). The second order solution of the diffracted waves due to the circular cylinder has been obtained by Kreibel (1990) and Chau and Taylor (1992...

... and the Fast Fourier Transform technique, the time-domain responses can be obtained. According to the arrival time of diffracted wave and direct wave, the major parameters that effect the dispersion phenomena, such as different embedded lengths and source point etc. have been studied. Moreover, an appropriate...

... spacing becomes smaller. The larger the spreading parameter, the larger the wave height inside an array. This can be due to a phase difference between the diffracted waves from each cylinder by the obliquely incident wave components. The contour lines of large wave height become long behind the array...

... ABSTRACT The second-order approximated solution of the velocity potential is derived, without using the Green function, to express the diffracted waves from the isolated cylinder in the directional sea condition at a constant water depth. Laboratory experiments are carried out to verify...

... on them with use of the radiation potential (Ghalayini and Williams, 1991). The wave profile, in particular run-up height on the cylinder surface, may be enlarged due to the nonlinear interaction of the diffracted waves generated by each cylinder. Thus, a theory which can evaluate the nonlinear behavior...
