AN EXPERIMENTAL STUDY ON NONLINEAR WAVE DYNAMICS: ROUGE WAVE GENERATION AND WAVE BLOCKING

Experimental Studies of Wave Transmission through Single Perforated Sheets and Upright Perforated Wave Filters

An experimental study of internal wave generation through evanescent regions

Internal waves are a complex phenomena that affect both the atmosphere and the ocean. Internal wave generation occurs uniquely in fluids which are stratified, or have varying density with respect to height. The natural frequency (N) is a fluid property that is defined by the rate of density change within the fluid. Internal waves are generated in stratified fluids when an excitation frequency (...

Wave group dynamics in weakly nonlinear long-wave models

Wave group dynamics is studied in the framework of the extended Korteweg-de Vries equation. The nonlinear Schrodinger equation is derived for weakly nonlinear wave packets, and the condition for modulational instability is obtained. It is shown that wave packets are unstable only for a positive sign of the coe cient of the cubic nonlinear term in the extended Korteweg-de Vries equation, and for...

EXPERIMENTAL INVESTIGATION OF OFFSHORE WAVE BUOY PERFORMANCE

The important characteristic of sea waves is their high energy density, which is the highest among renewable energy sources. Having up to 2700 km. of shoreline, Iran has a great potential in construction of offshore wave buoys (hereafter called OWB). In this article a OWB model with the possibility of assembling different buoy configurations is introduced. The system is exposed to regular and i...

Nonlinear Transfer From Wave-Wave Interactions

Nonlinear transfer from wave-wave i n teractions is an important term in the action-balance equation governing t h e e v olution of the surface-gravity-wave eld. Computation of this term, however, has hitherto been so consuming of computer resources that its full representation has not been feasible in nonparametric two-dimensional computer models of this e q u ation. This paper describes the i...
