Abstract

 In this study, the numerical simulations on two-dimensional dam break and three-dimensional collision between bore and a structure were conducted using OpenFOAM, which is one of the three-dimensional computational fluid dynamics tools. The validity of OpenFOAM was verified by comparing the numerical and experimental results. Furthermore, the validity of free surface analysis method based on the VOF method was examined in terms of the dynamic behavior of free surface. The numerical results revealed that OpenFOAM has good calculation accuracy for some hydraulic phenomena related to coastal and ocean engineering. It was also found that the parameter c_α, which indicates the control parameter on numerical diffusion, influences the dynamic behavior of free surface when the flow field largely changes.
