Composite Scattering of Ship on Sea Surface with Breaking Waves
The composite backscattering of the ship model on sea surface is investigated with the spilling breaking waves and ship bow waves. The spilling breakers are approximately modeled with the wedge-like waves, and the ship bow waves are simulated based on the Kelvin model. With the modified four-path model, each scattering component is evaluated with the high frequency approximation methods for the...
متن کاملLaboratory Measurements of Three-Dimensional Breaking Waves
Laboratory experiments were used to explore the influence of spatial focusing and diffraction on the evolution of unsteady, three-dimensional, deep-water wave-packets with a constant-steepness spectrum. The wave-packets were generated by thirteen independently programmed paddles and evolved to breaking near the midpoint of a 4m x 11 m test section. Detailed measurements of surface displacements...
متن کاملThe 3D Structure of Spilling Breakers
Nearly all calculations and measurements of breaking waves assume the wave profiles and flow fields are two-dimensional. Though this assumption may be correct before the waves become turbulent, once transition to turbulent flow begins, the real flow becomes highly three dimensional. The threedimensional structure and motion of the free surface is important for the dynamics of the breaking proce...
متن کاملWeakly-compressible SPH and Experimental modeling of periodic wave breaking on a plane slope
Breaking waves have ability to transport large quantities of sediment and significant impact on coastal structures morphology. Hence, modeling of wave breaking is an important subject in coastal and marine engineering. In this research, the periodic wave breaking process on a plane slope is studied experimentally and numerically. Laboratory experiments were conducted to record water surface ele...
متن کاملHigh Speed PIV of Breaking Waves on Both Sides of the Air-Water Interface
Wave breaking on the surface of the ocean results in significant transfer of mass, momentum, heat and energy across the air-sea interface. However, understanding the physics of these phenomena remains a challenge, as both the measurement and simulation of the relevant processes are highly complex. Recent numerical studies have begun to investigate the air-water coupling during the breaking proc...
