The Liquid Film Flow with Evaporation: Numerical Modelling
MATEC Web of Conferences, 2016 The flow of thin liquid layer on an inclined substrate is investigated numerically. The mathematical modelling is based on the Oberbeck-Boussinesq equations and the generalized conditions on the thermocapillary boundary simplified during the parametrical

Free Convection and Irreversibility Analysis inside a Circular Porous Enclosure
Entropy, 2003 We investigate the nature of heat transfer and entropy generation for natural convection in a two-dimensional circular section enclosure. The enclosure is assumed to fill with porous media.

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 ...

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.

Explicit Solutions of a Gravity-Induced Film Flow along a Convectively Heated Vertical Wall
The Scientific World Journal, 2013 The gravity-driven film flow has been analyzed along a vertical wall subjected to a convective boundary condition. The Boussinesq approximation is applied to simplify the buoyancy term, and similarity transformations are used on the mathematical model of

Adaptive Numerical Modeling of Tsunami Wave Generation and Propagation with FreeFem++
Geosciences, 2020 A simplified nonlinear dispersive Boussinesq system of the Benjamin–Bona–Mahony (BBM)-type, initially derived by Mitsotakis (2009), is employed here in order to model the generation and propagation of surface water waves over variable bottom.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The impact of three‐dimensional (3D) shortwave radiation on cloud condensate, size and lifetime is investigated using large‐eddy simulations coupled to an interactive land surface model (LSM). Results show 3D radiation produces higher cloud tops and greater cloud condensate than 1D radiation, resulting from larger downward shortwave fluxes ...

Neural‐BGC: An Observation‐Driven Emulator for Hybrid Physical‐Biogeochemical Modeling
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Coupled ocean‐biogeochemical models are essential for understanding marine ecosystems, yet they often suffer from persistent biases due to poorly constrained empirical parameters. To address this limitation, we introduce Neural‐BGC, an observation‐driven neural network emulator for hybrid physical‐biogeochemical modeling. Neural‐BGC is trained

Tunable 3D‐Printed Static Mixers for Gradient Bioprinting With High Cell Viability
Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.ABSTRACT The fabrication of native tissue‐like structures with gradual transitions in material properties, cell types, and growth factors remains a major challenge in biofabrication due to the lack of suitable methods. Mimicking the hierarchical organization of living tissues is essential for functional models, yet creating gradient, multimaterial ...

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.
