Oscillatory Shear Index (OSI) Values from Transient Blood Flow Simulations

OSI values quantify the directional oscillation of wall shear stress over a cardiac cycle, ranging from 0 to 0.5. The 5.5 KB dataset was created by Lei Zhengyao and last updated on May 28, 2026. Values were obtained from transient simulations using the final cardiac cycle to ensure periodic stability.

Use Cases

• Validate computational fluid dynamics (CFD) models of blood flow based on OSI values.
• Study the impact of inter-individual blood rheology variability based on different viscosity conditions.
• Analyze wall shear stress patterns in vascular simulations based on the oscillatory shear index.

Strengths

• Data is explicitly derived from the final cardiac cycle to ensure periodic stability.
• Includes results for below-normal, normal, and high blood viscosity conditions.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
