CaTSM: A Pseudo‐Spectral Thermodynamically Consistent Model of Compressible Flows
Journal of Advances in Modeling Earth Systems, 2022 We introduce a pseudo‐spectral algorithm that includes full compressible dynamics with the intent of simulating near‐incompressible fluids, CaTSM (Compressible and Thermodynamically consistent Spectral Model).

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.

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.

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

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.

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 ...

International Journal for Numerical Methods in Fluids, Volume 98, Issue 11, Page 1232-1243, November 2026.Employing the moving least‐squares aided finite element method (MLS‐FEM) allows detailed thermal analysis in complex porous structures, such as polymeric foams, where the conductive heat transfer mechanism governs in the solid matrix and the convective mechanism dominates within the gas‐filled voids.

Heat Transfer, Volume 55, Issue 7, Page 4554-4567, November 2026.ABSTRACT Several engineering problems involve the need to model conjugate heat transfer processes considering the temperature‐dependence of the material properties. Consequently, a simulation tool capable of modeling this process is of great interest. In this context, the present work proposes a thermal lattice Boltzmann method (TLBM) for modeling the ...
