概要

It measured the frictional resistance which is generated in the flow between two disks, one disk with the slits is rotating and the other fixed. Aqueous glycerin solutions are used as Newtonian fluids, and aqueous glycerin solutions adding polyacrylamide (Separan) are used as viscoelastic fluids. It was found that the moment is mainly concerned with the viscosity and the disk speed for Newtonian fluids, but for viscoelastic fluids it takes values greater than those estimated with the viscosity possessed by the solutions. Moment coefficient Cm is correlated with Reynolds number for Newtonian fluids, but larger for viscoelastic fluids than for Newtonian fluids. Also, as for the influence of the slits, the tendency which is different in Newtonian fluids and viscoelastic fluids appeard.
