Ahmed body surface data includes 3D surface geometry, pressure, and wall shear stress data for variations in the Ahmed body geometry and inlet Reynolds number. The dataset is authored by NVIDIA and was last updated on November 25, 2025. It is described as relatively small in size and intended for R&D and demonstration purposes, not for production.
Use Cases
- Teaching aerodynamic principles based on 3D surface geometry and pressure data
- Experimenting with CFD simulation validation based on wall shear stress data
- Demonstrating the effect of geometry variations on flow characteristics
- Analyzing the impact of inlet Reynolds number changes on surface forces
Strengths
- Includes multiple data types: 3D surface geometry, pressure, and wall shear stress
- Contains variations in both geometry and inlet Reynolds number
- Described as relatively small in size, reducing storage and computational demands
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Explicitly stated as not meant for production use
