Harnessing Machine Learning for Hybrid Constitutive Modelling of Viscoelastic Fluid Flows in Computational Rheology
J. L. Cummings, C. Fernandes, F. Dong +2
Recent advances in data-driven modelling have highlighted the potential of hybrid approaches which combine Tensor Basis Neural Networks (TBNN) with Universal Differential Equations…
Rheological behaviour and flow dynamics of Vitreous Humour substitutes used in eye surgery during saccadic eye movements
Andreia F. Silva, Francisco Pimenta, Manuel A. Alves +1
This work discusses the rheology of several vitreous humour (VH) substitutes used in eye surgery (perfluorocarbons and silicone oils) and their flow behaviour when subjected to sac…
Conjugate heat transfer in the unbounded flow of a viscoelastic fluid past a sphere
F. Pimenta, M. A. Alves
This work addresses the conjugate heat transfer of a simplified PTT fluid flowing past an unbounded sphere in the Stokes regime (). The problem is numerically solved wit…
Secondary flows of viscoelastic fluids in serpentine microchannels
Lucie Ducloue, Laura Casanellas, Simon J. Haward +5
Secondary flows are ubiquitous in channel flows, where small velocity components perpendicular to the main velocity appear due to the complexity of the channel geometry and/or that…
Numerical simulation of electrically-driven flows using OpenFOAM
Francisco Pimenta, Manuel A. Alves
In this work, we study the implementation of electrically-driven flow (EDF) models in the finite-volume framework of . The Poisson-Nernst-Planck model is…
