Animations for « Chaotic Fluid Mixing in Crystalline Sphere Arrays » by R. Turuban et al.

The animations are displayed in the order in which they appear along the paper’s and supp. mat.’s text. One of the files is a .wmv video file, the others are .gif. Click on an image to see the corresponding animation.

Anim1 :

Stretching and folding of a line of fluid particles (black line) which is a circle at initial time. The line is shown successively for increasing travel distance of the fluid inside the porous medium (in bead diameter unit).The initial circle is shown in red on top of the black line to indicate the scale.
The flow orientation is .

Anim2 :

Heteroclinic transverse connection of a 2D unstable manifold (in red) and a 2D stable manifold (in blue) in the BCC geometry. The flow orientation is .

Anim3 :

Heteroclinic smooth connection of a 2D unstable manifold (in red) and a 2D stable manifold (in blue) in the SC geometry.
The flow orientation is .

Anim4 :

 

Strongly hyperbolic 2D stable (non-transparent blue) and unstable (non-transparent red) manifolds emanating from a (non-transparent) sphere in the BCC packing, and the same manifolds emanating from adjacent (transparent) spheres.
The flow orientation is .

Anim5 :

 

Strongly hyperbolic 2D stable (blue) and unstable (red) manifolds emanating from a sphere in the BCC packing. Streamlines of the skin friction field are shown in red and blue on the sphere’s surface. Among them, the thick ones are separation (red) and reattachment (blue) critical and pseudo-critical skin friction streamlines; the color of the thick lines varies between deep red (respectively, blue) and white to represent the intensity of the divergence of the normalized skin friction field. The thin lines denote secondary (i.e., non-critical) streamlines of the skin friction field. The flow orientation is .
