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 ...

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 ...

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.

Employing the Moving Least‐Squares Aided Finite Element Method to Study Heat Transfer Phenomenon in Closed‐Cell Polymeric Foam

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.

Effect of shape and sizes of a local heat source on convective heat transfer in a square cavity [PDF]

Компьютерные исследования и моделирование, 2015
Numerical analysis of the effects of the local heat source shape on transient natural convection in a square enclosure has been carried out. The local heat source has rectangular, triangular and trapezoidal shape. The boundary value problem formulated in

New Thermal Lattice Boltzmann Method for Modeling Heat Transfer Problems Considering Temperature‐Dependent Properties

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 ...

Melt Production and Volatile Release From Thermochemical Mantle Plumes

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain poorly constrained.

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

Superpiles: The Impact of Mantle Temperature on Large Low Velocity Provinces

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Among the most prevalent features in Earth's deep mantle are the Large Low Velocity Provinces (LLVPs), hypothesized to be hotter and compositionally distinct from the surrounding mantle. LLVPs have previously been viewed as either active superplumes rising through the mantle or passive piles shaped by large scale convection.
