Numerical simulation of wave impact on the slab

In the paper, the wave generating and absorbing were introduced into the RANS equations as the source terms using the relaxation approach. A new module of the wave generating and absorbing function, which is suitable for FLUENT based on the volume of fluid method (VOF), was established. The computational results of the wave pressures on the bottom of the slab were validated for the different relative clearance by the experimental data. Good agreements were found. It is suggested that the numerical wave flume is capable of simulating the phenomenon of wave impact, especially the process of the negative pressure.
