Whirling Hexagons and Defect Chaos in Hexagonal Non-Boussinesq Convection
, 2003 We study hexagon patterns in non-Boussinesq convection of a thin rotating layer of water. For realistic parameters and boundary conditions we identify various linear instabilities of the pattern.

The Validity of Whitham's Approximation for a Klein--Gordon--Boussinesq Model [PDF]
SIAM Journal on Mathematical Analysis, 2016 In this paper we prove the validity of a long wave Whitham approximation for a system consisting of a Boussinesq equation coupled with a Klein-Gordon equation. The proof is based on an infinite series of normal form transformations and an energy estimate.

Electromagnetic Field Effects in Dialysis Membranes
Engineering Reports, Volume 8, Issue 5, May 2026.Hemodialysis efficiency strongly depends on membrane permeability, solute transport, and blood flow characteristics. External electromagnetic fields (magnetic and electric) can alter fluid dynamics, ionic motion, and nanoparticle‐assisted transport mechanisms within dialysis membranes.

On nonisothermal two‐fluid channel flows
Mathematical Modelling and Analysis, 2007 Two‐fluid channel flows arise in different kinds of coating technologies. The corresponding mathematical models represent two‐dimensional free boundary value problems for the Navier‐Stokes equations or their modifications.

On an Iterative Method for Approximate Solutions of a Generalized Boussinesq Model [PDF]
Journal of Mathematical Fluid Mechanics, 2009 An iterative method is proposed for nding approximate solutions of an initial and boundary value problem for a nonstationary generalized Boussinesq model for thermally driven convection of fluids with temperature dependent viscosity and thermal conductivity.

International Journal for Numerical Methods in Fluids, Volume 98, Issue 5, Page 557-577, May 2026.This study investigates the impact of uncertain parameters on Navier–Stokes equations coupled with heat transfer using the Intrusive Polynomial Chaos Method (IPCM). Sensitivity equations are formulated for key input parameters, such as viscosity and thermal diffusivity, and solved numerically using the Finite Element‐Volume method.

Storm Surge Barriers Reduce Seaward Sediment Supply to Lagoonal Estuaries
Earth's Future, Volume 14, Issue 5, May 2026.Abstract Numerical simulations with realistic forcing of fixed infrastructure for a proposed storm surge barrier for a lagoonal estuary, Jamaica Bay (New York, USA), are analyzed during typical forcing conditions to assess alterations to flow and sediment transport with the barrier open.
