Early Screening of Visual Processing Dysfunctions in Children Born Very or Extremely Preterm
Frontiers in Human Neuroscience, 2021 Introduction: Children with early brain damage or dysfunction are at risk of developing cerebral visual impairment (CVI), including visual processing dysfunctions (VPD), which currently remain largely undetected until school age.

Lattice Boltzmann simulation of droplet behaviour in microfluidic devices [PDF]
, 2008 We developed a lattice Boltzmann model to investigate the droplet dynamics in microfluidic devices. In our model, a stress-free boundary condition was proposed to conserve the total mass of flow system and improve the numerical stability for flows with ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Particle detection in VOF-simulations with OpenFOAM
SoftwareX, 2020 The aim of this work is to improve the particle detection in the phase field of volume of fluid (VOF) simulations included in OpenFOAM. The reliable evaluation of the particle properties is a prerequisite for coupling the VOF method for the primary breakup with an Eulerian–Lagrangian simulation of the secondary breakup.

Numerical Study on Passing Flow Through Circular Channels with Side [PDF]
مهندسی منابع آب, 2017 Side weir is used as a slot in the side of main channel to direct excess flows that are above the weir crest. Such structures are used in control of flow level in irrigation, drainage networks and urban sewage disposal systems.
