Abstract
The effects of strain hardening on the jet breakup due to a forced disturbance was studied. The relaxation times of the polymer solutions was quantified using the free jet extensional rheometer. The nature of capillary breakup due to an imposed disturbance was investigated as a function of disturbance wavelength-to-diameter ratio and initial disturbance amplitude. Results demonstrated that the time scales relevant to the drop formation from capillary breakup were the fluid relaxation time and the time scale of the disturbance growth.
