The relaxation time of entangled HPAM solutions in flow
Journal of Non-Newtonian Fluid Mechanics(2023)
摘要
•Apparent characteristic time for polyacrylamide (HPAM) under shear reported.•A commonly available controlled stress rheometer used.•Smooth evolution from reptation time to Rouse time with background shear rate seen.•Measured times coincide with a literature Rolie-poly calculation.
