【Abstract】 The anslytical cxpressins of lst and 2nd ordet solutions in frequency domain and the lincar soution in time domain are derived for tow -dimensional regular wave genetated by rocket flap wavemaket.Using the semi-Lagrangian time-stepping method.the mumetical simulation is also carried out to obtain the fully nonlinear transient solution, it crearly demonstrate the nonlinear property and the propagating process of the wave elevation. The ful-ly nonlinear resule is validated by the solutions in frequecy domain and the linear solution in time domain.Abstract The analytical expressions of 1st and 2nd order solutions in frequency domain and the linear solution in time domain are derived for two-dimensional regular wave generated by rocker flap wavemaker. Using the semi - Lagrangian time-stepping method. The numerical更多还原
