The dynamics of breaking progressive interfacial waves
Twoand three-dimensional numerical simulations are performed to study interfacial waves in a periodic domain by imposing a source term in the horizontal momentum equation. Removing the source term before breaking generates a stable interfacial wave. Continued forcing results in a two-dimensional shear instability for waves with thinner interfaces, and a convective instability for waves with thi...
متن کاملBreaking Waves in Population Flows
We test the controversial ideas about the role of corridors in fragmented animal habitats. Using simulation studies we analyze how fragmentation affects a simple prey-predator system and how the introduction of openings that connect the habitats changes the situation. Our individual based model consists of 3 levels: renewable prey food, as well as prey and predators that both have a simple econ...
متن کاملSubharmonic resonant excitation of edge waves by breaking surface waves
We have added a new Figure 3, where we show two frequency spectra. The first spectrum (Figure 3 a) is in absence of the breaking waves, where the first peak indicates the edge wave frequency and the second peak indicates the surface elevation frequency. The second frequency spectrum (Figure 3 b) is plotted in presence of breaking wave and indicates the suppression of the peak for the edge wave ...
متن کاملThe Study of Ultrasonic Waves on Dormancy-Breaking in Ferula Assa-Foetida, Ferula Gummusa and Myrtus Communis
Medical plants are adapted to different kinds of dormancy to survive in the worst situations. Regarding to ecological viewpoint, this kind of adaptation is very important in respect to restriction of genetic draft and decrease of genetic resource of medicinal plants. This leads to plant survival even after prolonged drought. Since some of them are endangered species and in the other hand increa...
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...
