Abstract

We use coarse-grained molecular-dynamics (MD) simulations to study the fragmentation of sodium dodecyl sulfate micelles under Poiseuille-like flow in a die-extruder geometry. The effect of flow confinement and wetting on spherical micelles is explored. We demonstrate that the interplay between flow and the wettability of the channel determines the size of daughter micelles inside the channel.
