Bayesian Conditional Diffusion Models for Versatile Spatiotemporal Turbulence Generation

no code implementations14 Nov 2023 Han Gao, Xu Han, Xiantao Fan, Luning Sun, Li-Ping Liu, Lian Duan, Jian-Xun Wang

A notable feature of our approach is the method proposed for long-span flow sequence generation, which is based on autoregressive gradient-based conditional sampling, eliminating the need for cumbersome retraining processes.

Flows Over Periodic Hills of Parameterized Geometries: A Dataset for Data-Driven Turbulence Modeling From Direct Simulations

1 code implementation3 Oct 2019 Heng Xiao, Jin-Long Wu, Sylvain Laizet, Lian Duan

However, a major obstacle in the development of data-driven turbulence models is the lack of training data.

Prediction of Reynolds Stresses in High-Mach-Number Turbulent Boundary Layers using Physics-Informed Machine Learning

no code implementations19 Aug 2018 Jian-Xun Wang, Junji Huang, Lian Duan, Heng Xiao

This study demonstrates that the PIML approach is a computationally affordable technique for improving the accuracy of RANS-modeled Reynolds stresses for high-Mach-number turbulent flows when there is a lack of experiments and high-fidelity simulations.
