Mixing of a Blob of Dye in A 3D Porous Media
Abstract
Successive experimental images of a blob of fluorescent dye (Rhodamine 6G) flowing through an indexmatched 3D porous media made of a random beadpack of monodisperse d = 2 mm diameter PMMA spheres. Time is normalized by the typical time τ it takes for the fluid to travel one d in the streamwise direction.
