Numerical Aspects of Turbulent Blood Flow in Aorta: A Systematic Review

Engineering Reports, Volume 8, Issue 9, September 2026.
The aim of this systematic review is to systematize the methodological approaches used in the state‐of‐the‐art literature, including the choice of turbulence models, validation methods, as well as the identification of the main hemodynamic parameters characterizing turbulent flow.

Boussinesq/Boussinesq systems for internal waves with a free surface, and the KdV approximation [PDF]

, 2011
We study here some asymptotic models for the propagation of internal and surface waves in a two-fluid system. We focus on the so-called long wave regime for one-dimensional waves, and consider the case of a flat bottom. Following the method presented in [

Thermal and Bioconvective Modeling and Analysis of Unsteady Cu‐Water Nanofluid Flow through Porous Media with Gyrotactic Microorganisms

Engineering Reports, Volume 8, Issue 9, September 2026.
The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

Boussinesq-Green-Naghdi Rotational Water Wave Theory

, 2014
A coastal ocean hydrodynamics modelling system has been created, with potential for future improvement. The system consists of a wave generation-absorbing system which initiates the exact desired hydrodynamic condition for computation; Boussinesq-Geen ...

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

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.

A Hybrid FEM–ML Framework for Magnetohydrodynamic Combined Convective Heat Transfer Performance of Hybrid Nanofluid Flow in a Horizontal Wavy Channel

Engineering Reports, Volume 8, Issue 9, September 2026.
The maximum heat transfer rate is observed at Ri = 10, Ha = 0, and ϕ = 0.06 under the default parameter settings for different boundary conditions. The proposed ANN model demonstrates good predictive and classification accuracy in estimating the average Nusselt number for both cases. ABSTRACT This computational study introduces a novel hybrid framework

Investigation of behavior of the dynamic contact angle on the basis of the Oberbeck-Boussinesq approximation of the Navier-Stokes equations

MATEC Web of Conferences, 2016
Flows of a viscous incompressible liquid with a thermocapillary boundary are investigated numerically on the basis of the mathematical model that consists of the Oberbeck-Boussinesq approximation of the Navier-Stokes equations, kinematic and dynamic ...

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.

Infragravity Waves Across a Steep‐Sloping Rough Rocky Seabed on the Inner Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Observations of infragravity (IG) waves were conducted from June to October 2023 along the rocky shores off China Rock, CA, on the inner shelf at depths of 8–13 m. The study examines inner‐shelf IG wave dynamics over rough, steep rocky shores and compares them with those over smoother, gentler sandy shores and coral reefs. IG energy correlated
