Random motions of irrotational gravity water surface waves on deep water are formulated using the so-called Wiener–Hermite functional series expansion, based on the ‘ideal random process’, i.e. the white noise. Such a procedure is known to diff

Deep-water gravity wave instabilities at large steepness

Autor: Alfred Ramamonjiarisoa, Christian Kharif

Publikováno v: Physics of Fluids. 31:1286

An extension of earlier computations on deep‐water gravity wave instabilities up to a wave steepness of 0.434 is performed to compare the relative strength of class I versus class II instabilities. The three‐dimensional class II, m=1 instabilitie
