Diffusion Models for Turbulent Flow Interpolation
Analysis
Key Takeaways
- •Applies conditional DDPMs to interpolate spatiotemporal flow sequences between sparse snapshots of turbulent flow fields.
- •Evaluates the method on 2D Kolmogorov Flow and 3D Kelvin-Helmholtz Instability (KHI).
- •Analyzes generated flow sequences using statistical turbulence metrics.
- •Focuses on capturing evolving flow statistics in the non-stationary KHI.
“The paper demonstrates a proof-of-concept generative surrogate for reconstructing coherent turbulent dynamics between sparse snapshots.”
