摘要

This article presented numerical results for 2D nonlinear wavemaking problems and compared them with laboratory data for validation. From simulated wave generation and propagation, we attempted to analyze the evolved waveform up to its final quasi-steady state in light of kinematic behaviors of wave-induced flow. A hybrid algebraic grid method was applied to construct the transient boundary-fitting grid system and transformed geometric coefficients were obtained by function differentiation. The transformed Laplace equation of stream function was discretized by the finite analytical method while the complete free-surface boundary conditions were treated instead by the finite difference scheme. The good consistency of our simulated waveforms with approximated solutions from short or long wave theories and with measurement ensures the proper applicability of this nonlinear wave model. Moreover, the grid technique developed in this model can be extensively utilized for many general moving-boundary problems.
