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.

Practical use of variational principles for modeling water waves [PDF]

, 2012
This paper describes a method for deriving approximate equations for irrotational water waves. The method is based on a 'relaxed' variational principle, i.e., on a Lagrangian involving as many variables as possible.

Thermal Analysis of Phase Change Material Based Energy Storage Module With Triply Periodic Minimal Surfaces

Energy Storage, Volume 8, Issue 4, June 2026.
ABSTRACT The thermal performance of two triply periodic minimal surface (TPMS) thermal Energy Storage modules, Diamond and Primitive, was investigated using computational fluid dynamics. The melting and solidification behaviors, as well as the charging and discharging characteristics, of the TPMS Energy Storage units were studied for various flow rates.

Inviscid incompressible limits of the full Navier-Stokes-Fourier system

, 2012
We consider the full Navier-Stokes-Fourier system in the singular limit for the small Mach and large Reynolds and Peclet numbers, with ill prepared initial data on the three dimensional Euclidean space. The Euler-Boussinesq approximation is identified as

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings

Heat Transfer, Volume 55, Issue 4, Page 2290-2312, June 2026.
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Global turbulence simulations of the tokamak edge region with GRILLIX

, 2019
Turbulent dynamics in the scrape-off layer (SOL) of magnetic fusion devices is intermittent with large fluctuations in density and pressure. Therefore, a model is required that allows perturbations of similar or even larger magnitude to the time-averaged

Slender vortex filaments in the Boussinesq approximation

Physics of Fluids
A model for the motion of slender vortex filaments is extended to include the effect of gravity. The model, initially introduced by Callegari and Ting [“Motion of a curved vortex filament with decaying vortical core and axial velocity,” SIAM J. Appl. Math.

Simulating Shallow Mesoscale Overturning Circulations in the Trades With Kilometer‐Scale Earth System Models

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Shallow mesoscale overturning circulations (SMOCs) are ubiquitous in the trades, primarily triggered by mesoscale convective heating and influencing the organization of shallow cumuli. Accurate representation of SMOCs and their co‐variability with moisture is crucial for capturing mesoscale cloud organization in models and improving climate ...

Natural convection flow near a vertical plate that applies a shear stress to a viscous fluid. [PDF]

PLoS ONE, 2013
The unsteady natural convection flow of an incompressible viscous fluid near a vertical plate that applies an arbitrary shear stress to the fluid is studied using the Laplace transform technique. The fluid flow is due to both the shear and the heating of
