Stokes flow in a converging-diverging channel gap: Eigenvalues, vortices and complex branching: Supplementary Material

Supplementary material to "Stokes flow in a converging-diverging channel gap: Eigenvalues, vortices and complex branching", submitted to the Journal of Fluid Mechanics. There homogeneous solutions to the stokes flow between two rollers are presented. The collection contains all figures shown in the publication and scripts to reproduce them. To do so it is necessary to run the "GeneratePlots.m" matlab-script. If output in png form is needed, the "export.sh" (requires an inkscape executable) can be run to convert the generated eps files. Additionally, also figures not displayed in the manuscript, of further solution branches and for pressure isocontours are contained in this collection. Furthermore, an applet is contained, "globalstreamlines.m", which can be started by simply typing "globalstreamlines" in a matlab application. Its purpose is to quickly visualize the streamlines in the nip between two rollers for arbitrary gap ratios and phases. This applet also enables the user to animate and record the evolution of streamlines over a range of gap ratios at a fixed phase and vice-versa. Two such animations are pre-recorded and contained in the collection.
