Rheological Data for a 2 wt% PIB Solution in Paraffin Oil

Nicholas King published this dataset on figshare in April 2026. It contains experimental rheological measurements, including frequency sweep and flow curve data, for a 2 wt% polyisobutylene solution in paraffin oil. The data is associated with a 2024 Journal of Fluid Mechanics article on elasto-inertial instability.

Use Cases

• Modeling shear-thinning viscoelastic fluid behavior based on steady-state viscosity and first normal stress difference coefficient data.
• Analyzing material response under oscillatory shear based on the frequency sweep data.
• Validating computational fluid dynamics models for viscoelastic flows using experimental flow curve data.
• Studying elasto-inertial instabilities in torsional flows using the provided rheological properties.

Strengths

• Data is directly linked to a peer-reviewed publication in the Journal of Fluid Mechanics (2024).
• Published under a permissive CC-BY-4.0 license.
• File size is 14.9 KB, ensuring quick download and inspection.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset's small size (14.9 KB) indicates a very limited experimental scope.
