Flow kinematics for equatorial coupled surface and internal waves
David Henry, Rossen Ivanov, Gabriele Villari
We study the propagation of coupled surface and internal equatorial internal waves. A model of two vertically stratified fluid layers with different constant densities is employed.…

Rotational flow underlying coupled surface and internal waves. I: Eulerian perspective
David Henry, Rossen I. Ivanov, Zisis N. Sakellaris
In this paper we examine the flow generated by coupled surface and internal small-amplitude water waves in a two-fluid layer model, where we take the upper layer to be rotational (…

Higher-order integrable models for oceanic internal wave-current interactions
David Henry, Rossen I. Ivanov, Zisis N. Sakellaris
In this paper we derive a higher-order KdV equation (HKdV) as a model to describe the unidirectional propagation of waves on an internal interface separating two fluid layers of va…
