sandbox/walmetz/README
Hi, I’m Malo WALMETZ, currently studying at Arts et Métiers (ENSAM) and Sorbonne University (2026).
My sandbox is based on my M2 internship with Francesco Picella (d’Alembert Institute) and Jean-Christophe Robinet (DynFluid). Thus, every line of code is dedicated to superhydrophobicity and has been written between march and july 2026.
If you need a further look at anyone of my graph, checkout my GitHub. They are traced with matplotlib, with codes on my laptop, and I’d be pleased to share them. I didn’t find another solution : since I cannot run the codes on basilisk.fr, gnuplot can’t work here.
Codes
About the simple 2D cylinder in a fluid flow
This parti is only made to validate the classical 2D cylinder flow, and for me to understand how Basilisk works.
- Validation of a modified version of Picella’s code based on the (Cd,Re) diagram : 2D_cylinder
About slip-length
This is, in my case, the simplest way to model superhydrophobicity.
- Validation of twitkamp embed navier condition by using it in this code and comparing it to Legendre et al.,2009
About multiphase flows
link to multiphase flows folders
We want to go as close as possible to reality, bringing up multiphase flows.
- The first step to reality is a “frozen” bubble around the cylinder. In itself, this case is everything but realistic but it will help us for the dynamic bubble case.
- The first thing I tried was this dynamic bubble around a cylinder. It didn’t work well so I moved on…
To do list
This part is only for myself ;)
Pour tous les cas : analyse de longueur de recirculation pour comparaison avec Enzo. Se renseigner sur paraview.
SLIP 2D :
- plot Cd=f(Re)
- bifurcation ?
NO SLIP 3D :
!! Pouvoir faire tourner haut L0, haut maxlevel !!
plot Cf=f(Re)
Etude modale ? Référer à Williamson
Condition d’arrêt
maxlevel variable en fonction de convergence (donc cond d’arrêt)
SLIP 3D :
