Abstract

Optical PIV measurements were aimed at studying fluid mechanical problems in a coal flotation process. Since the associated solid phase (coal/mineral) develops a high degree of light extinction, a solution had to be found for allowing a high concentration of the solid phase without losing the optical access for the PIV light sheet. The solution consisted in simulating the solid phase with glass spheres whose refractive index was matched by an organic liquid in the two-phase system.
