About the Lab
Professor Joongoo-Jeon Jeon's research lab specializes in computational fluid dynamics and machine learning for turbulent flow prediction, focusing on data-driven modeling of complex, high-dimensional fluid systems. The lab explores generative deep learning models—particularly diffusion models—to improve the accuracy and physical consistency of long-term predictions in two- and three-dimensional turbulence. Key research directions include the development of physics-informed neural networks, uncertainty quantification in turbulent flow forecasting, and the preservation of fine-scale structures and energy spectra in predictive models. The lab also investigates time-interval effects and error accumulation in autoregressive prediction frameworks, aiming to bridge the gap between machine learning generalization and physical fidelity in fluid dynamics.

1This study investigates the impact of time increments on the autoregressive prediction of two-dimensional turbulence slices extracted from three-dimensional direct numerical simulations, comparing a U-Net with a diffusion-based generative model. Experiments demonstrate that the diffusion model significantly outperforms the deterministic approach, reducing the rollout-averaged mean squared error by 28.3% and relative energy error by 61.9%. Notably, the generative model effectively mitigates the s
