The Miles Theorem and New Particular Solutions to the Taylor--Goldstein Equation [PDF]

Учёные записки Казанского университета: Серия Физико-математические науки, 2016
The linear stability problem of steady-state plane-parallel shear flows of a continuously stratified inviscid incompressible fluid in the gravity field between two immovable impermeable solid planes is studied in and without the Boussinesq approximation.

A Non-Hydrostatic Depth-Averaged Model for Hydraulically Steep Free-Surface Flows

Fluids, 2017
This study describes the results of a numerical investigation aimed at developing and validating a non-hydrostatic depth-averaged model for flow problems where the horizontal length scales close to flow depth.

Convective layered flows of a vertically whirling viscous incompressible fluid. Velocity field investigation

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
This article discusses the solvability of an overdetermined system of heat convection equations in the Boussinesq approximation. The Oberbeck-Boussinesq system of equations, supplemented by an incompressibility equation, is overdetermined.
