Internal Soliton in Two-Layered Stratified Fluids

Yuji SUGIHARA, Nobuhiro Matsunaga, Kazuki Sakai, Hiroyuki Honji

Abstract

An internal soliton in two-layered stratified fluids has been investigated by means of flow visualization. The relationship between the phase speed of soliton and its amplitude has been obtained experimentally. It has been also found that steady waves form behind the internal soliton traveling alongthe interface of a stratified fluid. The waves are of similar characteristics tothe lee waves which are observed behind a mountain in stratified atmosphericflow.
