چکیده
|
A two-way coupling algorithm for wave-current interaction is developed and implemented into a nearshore circulation model to investigate the effects of fully wave-current interaction on irregular wave transformation over an elliptic shoal. the wave field is simulated by a spectral wave model wabed,and the wave-induced current is solved by a quasi-three-dimensional model wincm. the surface roller effects are represented in the formulation of surface stress,and the roller characteristics are solved by a roller evolution model. the proposed two-way coupling algorithm can describe both the generation of wave-induced current and the current-induced wave transformation,which is more physically reasonable than the one-way approaches. the model test with a laboratory experiment shows that wave-induced currents have an important influence on the wave transformation,for example,the wave energy defocusing due to the strong jet-like current along the centerline of the shoal. it is revealed that the accuracy of simulated wave field can be significantly improved by taking into account the two-way wave-current interaction. © 2012 jinhai zheng et al.
