I need to prepare a stable inexpensive liquide to fill up the pores of a porous medium made of transparent glass beads, for PIV measurements. The liquid must be a shear-thinning one. A list of Newtonian liquids is available in Budwing, Exp. in Fluids 1994, and in Hassan and Dominguez, Nucl. Engng and Des., 2008. Does anybody have experience in adding, e.g., Xhantan gum to Potassium Tiocianate or to any other fluid in the lists of the two papers?
I haven't done myself in the lab (some tries for cuisine ;) , though ); some of my colleagues in the Faculty of Medicine made some query to us some years ago, this paper
http://www.ar.ethz.ch/cgi-bin/AR/view?DOI=10.3933/ApplRheol-17-44251
and this one (fully available)

may help, especially the second one seems to be describing the test in detail. I can check with my colleagues whether they finally got the essays running.
Un abrazo desde Cordoba,
María José
Ciao Maria, thanks for the suggestion. Yes please, let me know about the final results of the essays.
The first paper seems also interesting but I cannot access it. I would appreciate if somebody could forward it.
Besos
