Elongational Viscosity Rheological Parameter Study

reportActive / Technical Report | Accession Number: ADA125265 | Open PDF

Abstract:

The physics of drop breakup is considered, and an analysis suggest that the elongational viscosity of the drop may control its disruption to smaller droplets. An experimental system has been designed which permits the study of the elongational rheology of liquids of interest. In the experiment, the rate of collapse of a gas bubble within the test liquid is measure. Preliminary data are obtained which indicate the feasibility of performing a precise experiment. Features of the experimental system that require improvement are pointed out and discussed.
