Two engineering students, co-authors of a scientific article published in Physical Review E
Bartholomé Soltner and Adrien Petit, 2nd year engineering students, are co-authors of the scientific article “Enhanced coarsening induced by pore confinement”, published in the American Physical Society's journal Physical Review E.
Supervised by doctoral student Ali Salamé and Olivier Pitois, Director of Research at the Navier laboratory and a teacher at the School, they contributed to the work that gave rise to this publication as part of their 1st year research course.
This optional course enables students to take part in a research project supervised by a researcher, while benefiting from laboratory visits and methodological seminars, to familiarize themselves with research practices and develop practical and analytical skills.
Soils, porous media by nature, can have their properties enhanced by the injection of liquid foam.
Thanks to highly precise optical measurements, the students and their supervisors were able to study the distribution of liquid foam in the porosity of the soil. They revealed an unexpected phenomenon: the average bubble size of a liquid foam confined in a porous medium increases much faster than predicted by theoretical models. A physical mechanism never before identified!
