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 no-slip cylinder
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
- An extension of Antoon’s 3D cylinder, to try to study modes A and B (in this code). But it’s not precise… maybe it would be with an extreme mesh :|
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…
- The last thing I tried is a “notch”. It needs an experimental reference (check out Santoromito’s PhD). It isn’t superhydrophobic but we created it to study the influence of external pressure.
