Laboratory 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 کاملThree-dimensional Large Eddy Simulation of air entrainment under plunging breaking waves
The scope of this work is to present and discuss the results obtained from simulating three-dimensional plunging breaking waves by solving the Navier-Stokes equations, in air and water, coupled with a dynamic subgrid scale turbulence model (Large Preprint submitted to Coastal Engineering 23 January 2006 ha l-0 02 94 09 2, v er si on 1 8 Ju l 2 00 8 Author manuscript, published in "Coastal Engin...
متن کاملEvaluation of turbulence closure models under spilling and plunging breakers in the surf zone
Turbulence closure models are evaluated for application to spilling and plunging breakers in the surf zone using open source computational fluid dynamics software. A new library of turbulence models for application to multiphase flows has been developed and is assessed for numerical efficiency and accuracy by comparing against existing laboratory data for surface elevation, velocity and turbule...
متن کاملVoid Fraction Disturbances in Bubbly
-The paper is concerned with the flow of dispersions of gas bubbles in liquid, with bubble sizes such that the inertia forces on the bubbles are of importance to the dynamics. One-dimensional conservation equations are derived, which govern the flow when the deviations from the uniform state are small. These are used to describe the features of the propagation of void fraction disturbances, and...
