Wave Energy Dissipation of Spilling and Plunging Breaking Waves in Spectral Models
Journal of Marine Science and Engineering, 2022 On the basis of field experiments and modeling, the dependence of the dissipation of the energy of waves breaking by plunging and spilling on the frequency of wave spectra was investigated. It was shown that the modeling of wave breaking should take into

The Oberbeck–Boussinesq approximation in critical spaces [PDF]
Asymptotic Analysis, 2013 In this paper we study the validity of the so-called Oberbeck–Boussinesq approximation for compressible viscous perfect gases in the whole three-dimensional space. Both the cases of fluids with positive heat conductivity and zero conductivity are considered. For small perturbations of a constant equilibrium, we establish the global existence of unique

On the numerical approximation of Boussinesq/Boussinesq systems for internal waves
Numerical Methods for Partial Differential Equations, 2023 AbstractThe present paper is concerned with the numerical approximation of a three‐parameter family of Boussinesq systems. The systems have been proposed as models of the propagation of long internal waves along the interface of a two‐layer system of fluids with rigid‐lid condition for the upper layer and under a Boussinesq regime for the flow in both ...
