Laboratory PIV measurements of wave breaking on a beach
نویسندگان
چکیده
Experiment were conducted in the ESIM wave tank in Marseilles in order to study the space/time evolution of the flow field under waves breaking on an 1/15 beach slope. Fluid particles velocities were measured at different depths, before, during and after the breaking event using the Particle Imaging Velocimetry (PIV) technique. The mean and fluctuant components of the flow were calculated.

Particle Image Velocimetry (PIV) measurements were performed in a wave tank under regular water waves propagating and breaking on a 1/15 sloping beach. To obtain more accurate measurements, the domain from the initiation of the breaking to the swash zone is splited in fourteen overlapping windows. The full field is reconstructed at each time step by gathering the fourteen synchronized PIV field...

In this article, a numerical meshless method called Weakly Compressible Smoothed Particle Hydrodynamic (WCSPH) is used to simulate the solitary wave breaking process on the beach. The present model is a two dimensional model that considers the fluid weakly compressibility. This model solves the viscous fluid equations to obtain velocity field and density and solves the equation of state to obta...
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...
