Generative prediction of flow fields around an obstacle using the diffusion model
Jiajun Hu, Zhen Lu, Yue Yang
We propose a geometry-to-flow diffusion model that utilizes obstacle shape as input to predict a flow field around an obstacle. The model is based on a learnable Markov transition…

Fine-tuning a Large Language Model for Automating Computational Fluid Dynamics Simulations
Zhehao Dong, Zhen Lu, Yue Yang
Configuring computational fluid dynamics (CFD) simulations typically demands extensive domain expertise, limiting broader access. Although large language models (LLMs) have advance…

Synergy of turbulence and thermo-diffusive effects on the intermittent boundary-layer flashback of swirling flames
Shiming Zhang, Zhen Lu, Yue Yang
We simulated the intermittent boundary-layer flashback (BLF) of hydrogen-enriched swirling flames using large-eddy simulation (LES) with the flame-surface-density (FSD) method. Thr…
