From Champagne to Confined Polymer:Natural and Artificial Bubble Nucleation
Carlos Arauz-Moreno, Keyvan Piroird, Elise Lorenceau
In this study, we present an experimental work on bubble nucleation and growth using a model system comprised of viscoelastic polyvinyl butyral confined in a Hele-Shaw cell geometr…
Bubble growth in a confined heated polymer: the example of safety glass
Carlos Arauz-Moreno, Keyvan Piroird, Elise Lorenceau
Laminated safety glass (LSG) is a composite assembly of glass and polyvinyl butyral (PVB), a viscoelastic polymer. LSG can be found in building facades, important landmarks around…
Role of evaporation rate on the particle organization and crack patterns obtained by drying a colloidal layer
Keyvan Piroird, Véronique Lazarus, Georges Gauthier +3
-- A scientific hurdle in manufacturing solid films by drying colloidal layers is preventing them from fracturing. This paper examines how the drying rate of colloidal liquids infl…
Capillary Flow of Oil in a Single Foam Microchannel
Keyvan Piroird, Élise Lorenceau
When using appropriate surfactants, oil and aqueous foam can be intimately mixed without the foam being destroyed. In this Letter, we show that a foam, initially free of oil, can d…
Reshaping and Capturing Leidenfrost drops with a magnet
Keyvan Piroird, Baptiste Darbois Texier, Christophe Clanet +1
Liquid oxygen, which is paramagnetic, also undergoes Leidenfrost effect at room temperature. In this article, we first study the deformation of oxygen drops in a magnetic field and…
Paramagnetic Leidenfrost Drops
Keyvan Piroird, Baptiste Darbois Texier, Christophe Clanet +1
We present a fluid dynamics video showing the behavior of drops of liquid oxygen, at room temperature. Due to their low boiling point, these drops levitate on a cushion of their ow…
