Drag modelling for flows through assemblies of spherical particles with machine learning: A comparison of approaches
Julia Reuter, Hani Elmestikawy, Sanaz Mostaghim +1
Drag forces on particles in random assemblies can be accurately estimated through particle-resolved direct numerical simulations (PR-DNS). Despite its limited applicability to rela…
A new paradigm for computing hydrodynamic forces on particles in Euler-Lagrange point-particle simulations
Berend van Wachem, Hani Elmestikawy, Akshay Chandran +1
Accurate prediction of the hydrodynamic forces on particles is central to the fidelity of Euler-Lagrange (EL) simulations of particle-laden flows. Traditional EL methods typically…
Self-sorting of bidisperse particles in evaporating sessile droplets
Aman Kumar Jain, Fabian Denner, Berend van Wachem
This study investigates the dispersion and self-sorting dynamics of bidisperse particles, i.e., a mixture of two distinct particle sizes, during the evaporation of ethanol droplets…
Explicit Predictor-Corrector Method for Nonlinear Acoustic Waves Excited by a Moving Wave Emitting Boundary
Sören Schenke, Fabian Sewerin, Berend van Wachem +1
We present an explicit finite difference time domain method to solve the lossless Westervelt equation for a moving wave emitting boundary in one dimension and in spherical symmetry…
A unified algorithm for interfacial flows with incompressible and compressible fluids
Fabian Denner, Berend van Wachem
The majority of available numerical algorithms for interfacial two-phase flows either treat both fluid phases as incompressible (constant density) or treat both phases as compressi…
Quantifying the errors of the particle-source-in-cell Euler-Lagrange method
Fabien Evrard, Fabian Denner, Berend van Wachem
The particle-source-in-cell Euler-Lagrange (PSIC-EL) method is widely used to simulate flows laden with particles. Its accuracy, however, is known to deteriorate as the ratio betwe…
Numerical modelling of shock-bubble interactions using a pressure-based algorithm without Riemann solvers
Fabian Denner, Berend van Wachem
The interaction of a shock wave with a bubble features in many engineering and emerging technological applications, and has been used widely to test new numerical methods for compr…
Transient structures in rupturing thin-films: Marangoni-induced symmetry-breaking pattern formation in viscous fluids
Li Shen, Fabian Denner, Neal Morgan +2
In the minutes immediately preceeding the rupture of a soap bubble, distinctive and repeatable patterns can be observed. These quasi-stable transient structures are associated with…
Capillary waves with surface viscosity
Li Shen, Fabian Denner, Neal Morgan +2
Experiments over the last 50 years have suggested a tentative correlation between the surface (shear) viscosity and the stability of a foam or emulsion. We examine this link theore…
