Dataset on velocity fields around single and interacting particles sinking in aqueous xanthan gum solutions

This dataset contains (1) 2D2C velocity fields around spheres sinking in dispersions of xanthan gum (XG) in distilled water (2) shear and extensional rheological characteristics of these non-Newtonian dispersions. Experiments comprised two test solutions containing 0.75 and 1.25 g/L of XG. The settling of three types of spheres was examined in a settling column using Particle Image Velocimetry (PIV).
