Three-layer water flows: Dirichlet-Neumann operators and approximations

Rossen Ivanov, Calin-Iulian Martin

The object of investigation in this paper are the nonlinear equations of motion for two-dimensional inviscid water flows with piecewise constant density stratification in a three-l…

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 (…

Modelling intermediate internal waves with currents and variable bottom

Rossen Ivanov, Lyudmila Ivanova

A model for internal interfacial waves between two layers of fluid in the presence of current and variable bottom is studied in the flat-surface approximation. Fluids are assumed t…

Modelling surface waves on shear current with quadratic depth-dependence

Conor Curtin, Rossen Ivanov

The currents in the ocean have a serious impact on ocean dynamics, since they affect the transport of mass and thus the distribution of salinity, nutrients and pollutants. In many…
