Viscoelastic properties of Xanthan gum (0.3% to 0.6%) at different gas injection rate (0.5LPM to 2LPM)

The Xanthan gum samples were measured at four different gas flow rates (0.5 LPM, 1.0 LPM, 1.5 LPM & 2.0 LPM). The dynamic time sweep measurements were generated from the Xanthan gum sample first without gas at 0.15% strain across 1500 seconds.

Then the sample was conditioned and the gas was injected for 20 minutes before the measurement at similar conditions. Similarly, the dynamic creep test measurements were generated from the xanthan gum sample first without gas at 3 pa stress across 1500 seconds. The measurements were carried out on a DHR-3 rheometer (TA-Instruments), equipped with custom made cup.
