摘要：

The law of uniform current effects on the characteristics of regular waves and its uncertainty is investigated for wave-current interactions. Firstly, relevant tests of the interaction of regular waves and currents were conducted in the circulating water channel at Shanghai Jiao Tong University. Numerical simulation based on Reynolds-Averaged Navier-Stokes (RANS) equations was then carried out to solve the problem of regular-wave-current interaction. Finally, the simulation results were used to perform the uncertainty analysis. It is concluded that wave heights are low and wave peaks and troughs are flat in the co-current case. However, completely opposite phenomena are observed in waves with countercurrents. The waves are blocked when the velocity of the countercurrent increases to 0.6 m/s. Moreover, the simulated results are more sensitive to grid size than time steps in both no-current and co-current cases. Furthermore, compared with the no-current case, the influence of grid size and time step are clearer in the co-current cases. Copyright ©2021 Journal of Harbin Engineering University.
