Peldom Elongational ViscosityR-042

Description

Capillary rheology measurements are performed using using a zero L/D orifice die and a 20 L/D die. A range of flow rates is used, attempting to cover a shear rate range of 10-10,000/s. The entrance losses are obtained from these measurements. The Peldom software is used to simulate this experiment and the elongational viscosity v. elongation rate data are extracted.
