Abstract

  In this study, the wave-current interaction and its mechanism are investigated in relation to its crossing angle using newly developed numerical model which is able to generate oblique waves smoothly.Numerical analysis has been conducted to analyze the wave height distribution and velocity field due to the wave-current interaction. First, numerical method has been verified in comparison with exiting experimental results on the wave-current interaction. It is shown that there is a good agreement between numerical and experimental results.Also, numerical results show that the wave height decreases with increasing current speed. It can be pointed out that current speed and incident wave period have a little effect on wave height as crossing angle between wave and current becomes smaller.
