... the wave slamming of braces under towing conditions too. The sensitivities of the wave slamming at different wave steepness and wave direction angles under the towing conditions were analyzed. It is found that wave steepness and wave direction angles have significant effects on the wave slamming pressure...

... nonlinear trapped waves induced by weak resonant interactions of water waves are identified by the apparent variation of the higher harmonic components. It is found that the nonlinearity grows with the increase of trapped modes and wave steepnesses but has little effect on the reflection. INTRODUCTION...

... of nonlinearity on the resonant wave patterns is investigated. It is found that, if the steepness is large enough, the crestlines would curve and even split into two shorter crests. Its curvature extent is proportional to the primary waves' steepness and the propagation distance. By contrast, the nonresonant...
