An idealised model of convective hydration of the tropical tropopause layer. Part I: Model formulation and diagnostic approach

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We formulate an idealised model of convective overshoots that hydrate the tropical tropopause layer. We consider large‐eddy simulations of a turbulent buoyant plume that penetrates into a stably stratified layer carrying temperature‐dependent tracers that represent water vapour and ice.

Macroscopic Convective Fluid Flows Arising From Binding of Ions and Small Molecules to Proteins

Small, EarlyView.
The interaction of ions or small molecules with proteins causes convective flows due to the displacement of water from the hydration shell. As shown, the replacement of the nickel ion removed from urease by EDTA pre‐treatment results in binding‐induced convective fluid flow.

Layered Radial Aquifer Model for Open‐Pit Mine Closure with Managed Aquifer Recharge

Groundwater, EarlyView.
A radially symmetric layered aquifer model (unconfined–aquitard–confined) coupled to a pit‐lake water balance is developed to screen managed aquifer recharge (MAR) after open‐pit mine closure. Dimensionless type curves quantify trade‐offs between pit recovery time, pumping/recycling, and unconfined mounding as functions of aquifer time scales, aquitard

Mathematical Modelling of the Evaporating Liquid Films on the Basis of the Generalized Interface Conditions

MATEC Web of Conferences, 2016
The two-dimensional films, flowing down an inclined, non-uniformly heated substrate are studied. The results contain the new mathematical models developed with the help of the long-wave approximation of the Navier-Stokes and heat transfer equations or ...

Approximation of ill-posed boussinesq equations [PDF]

Dynamical Systems, 2004
In this paper we compare the dynamics on the centre manifold of the solutions of an ill-posed Boussinesq equation with a well-posed version. We show that the dynamics in the centre manifold of the ill-posed equation tracks the dynamics of the well-posed equation. Our results give partial justification to the long-wave perturbation theory.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

Communications on Pure and Applied Mathematics, Volume 79, Issue 12, Page 2435-2490, December 2026.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

A numerical investigation of high-Reynolds-number constant-volume non-Boussinesq density currents in deep ambient [PDF]

, 2011
The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents, released from a lock of height h0 and length x0 into a deep ambient and spreading over horizontal flat boundaries, is considered.

Scattering Of Internal Waves By Vertical Barrier In A Channel Of Stratified Fluid

International Journal of Applied Mechanics and Engineering, 2015
The problem of two dimensional internal wave scattering by a vertical barrier in the form of a submerged plate, or a thin wall with a gap in an exponentially stratified fluid of uniform finite depth bounded by a rigid plane at the top, is considered in ...
