My name is Hazel Inglis, and I am currently working on an academic project focused on the rheological characterization of hydroxypropyl guar (HPG) solutions, particularly under conditions relevant to hydraulic fracturing.

I am looking for experimental data showing the variation of shear stress with shear rate (or strain rate), preferably in the form of tables and graphs. I am especially interested in datasets that also include apparent viscosity as a function of deformation or flow velocity. My goal is to fit these data to the Herschel–Bulkley model and to analyze how these properties influence momentum transport and the general rheological behavior of the fluid.

If you could recommend any reliable sources, publications, or even share any available experimental datasets related to HPG, I would greatly appreciate it. Any guidance or suggestions would be incredibly helpful.
