Nonlinear Dynamo in Obliquely Rotating Stratified Electroconductive Fluid in an Uniformly Magnetic Field

East European Journal of Physics, 2020
In this paper, we investigated a new large-scale instability that arises in an obliquely rotating convective electrically conducting fluid in an external uniform magnetic field with a small-scale external force with zero helicity.

Redistribution of Sediment and Particulate Mercury Within Upstream Reaches of Galveston Bay in Response to Hurricane Harvey

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Extreme storms and flooding can remobilize legacy contaminants stored in the sediment bed; however, event‐scale models that resolve the transport of these materials remain underdeveloped. This study developed a numerical model of contaminated sediment transport during Hurricane Harvey (August 2017), which struck the upstream reaches of ...

Wave Energy Transfer in Shallow Water: Numerical Investigation of Slope and Offshore Wave Condition Effects

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract This study advances the understanding of nonlinear wave interactions in shallow water by numerically quantifying how foreshore slope and offshore conditions influence energy transfer and wave evolution over a broad range of conditions. Two non‐hydrostatic models, SWASH and XBeach, are validated against physical experiments and applied across a

Thermal dissipation of two-step combustible tangent hyperbolic fluid with quadratic Boussinesq approximation and convective cooling

Results in Materials
This study explores thermal criticality and dissipation involving a two-step reaction in a hyperbolic tangential fluid flow and quadratic Boussinesq approximation to model the complex internal heat transfer mechanisms during combustion.

Ageostrophic Velocities of Curved Ocean Fronts

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract Ageostrophic velocities at ocean fronts play a key role in ventilating the upper ocean. The overturning circulation driven by cross‐front ageostrophic flow is widely recognized as the major mechanism of vertical transport, but the role of along‐front ageostrophic velocities remains underrepresented in existing theory.

Couette-Hiemenz exact solutions for the steady creeping convective flow of a viscous incompressible fluid with allowance made for heat recovery

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2018
In this paper, we study the steady creeping convective flow of a viscous incompressible fluid in the thin infinite layer. The study of the fluid flow is based on the exact solutions class for the Oberbeck-Boussinesq equations in the Stokes approximation ...

Numerical simulation of high-swirl flow in axial turbine stage

EPJ Web of Conferences, 2016
This article deals with numerical modelling of flow in an axial turbine stage with prismatic blades which are not equipped with shroud. In this case flow through a radial gap above and below ends of blades leads to generation of strong secondary vortices

Weakly Nonlinear Instability of a Convective Flow in a Plane Vertical Channel

Fluids
The weakly nonlinear stability analysis of a convective flow in a planar vertical fluid layer is performed in this paper. The base flow in the vertical direction is generated by internal heat sources distributed within the fluid.
